When you pick up your Caravan / RV from our offices Caravans for Hire will give you a "walk through" of the unit you selected. During the outside walk around we will show you how to work several parts of the RV. Windows — We will go through each window to make sure it has its screen and closes properly. Doors — We will check every door opens and closes properly and make sure that you have the matching key. Baggage Compartments — We will open and close each door making sure the doors close tightly and they are align. You will get a key that locks the doors. We will verify that compartment lighting works properly. Engine Compartment Door — We will open and close the door checking for alignment and latches to make sure that the door closed during RV operation. You will get a key that locks the door. Generator Compartment/Door — We will check out the compartment that holds the generator closely to insure that everything is tight and rattle free. We will make sure the exhaust from the generator is not directly under any slide out or window that might be used for ventilation. If the generator is on a powered slide, we will operate it several times to make sure it extends and retracts well. Fuel Doors — We will inspect the fuel doors for proper locking and to verify the operation of the fuel caps. We will verify that you know how to properly fill the fuel tank. Please read our Fuel, Oil & Propane page for more information. Utility Compartment — Together we'll inspect this compartment closely to understand how each valve or fitting works. We'll make sure you understand how the sewer hose is properly stored. Understand the proper function of the black and gray water valves. Understand tank flushing and how it operates. Understand the telephone and cable connections. If there is an electric cable reel, we will extend and retract it several times to insure proper operation. Understand where the low point drains are for the fresh water. Propane — Check the propane compartment to verify that the ventilation downward is proper since propane is heavier than air. There should be no possible way for propane to enter into the RV or any other compartment. Locate and understand the operation of the main shut off valve. Please read our Fuel, Oil & Propane page for more information. Battery — We will check the battery compartment to verify that it too is ventilated and that all slide mechanisms work properly. We will verify that no battery cables are rubbing on any part of the frame because that will eventually end up with a short circuit and possible fire. Understand the battery type provided and how to maintain them. Please read our Battery page for more information. Paint — We will carefully check the paint finish on the RV. Look at places where vinyl film is used to make sure it is free of any air bubbles. Look closely where masking tape was used for paint graphics to make sure there is no over-spray. Carefully check for surface smoothness and any place when paint coverage is marginal or where there are bubbles. Tires and Wheels — We will closely inspect the tires and wheels and understand the proper pressure. We will verify the torque of the lug nuts. Please read our Tires page for more information. Awnings — We will extend and retract each awning paying particular attention to how the awning is locked in the retracted position. We will make sure all springs, lock, supports work well and are properly aligned. Please read our Awnings page for ore information. Before you leave on your trip we will inspect all air and or hydraulic lines, wiring, shock absorber attachments, and in general every place that a wire or pipe could rub against something that will cause a problem later. We will look at exhaust pipe routing to make sure that nothing is going to get too hot from radiated heat when you are "climbing that long grade on a hot day". We will make sure the exhaust pipe is properly shielded from propane lines and tank. All wiring and piping will be properly fastened. We will check the operation of each wheel brake for proper adjustment and operation. Check for any fluid leakage. Hydraulic, transmission, fuel, oil, coolant, etc should be included in this list. We will check the engine drive belts. If your RV includes a slide-out or slide-outs then we will spend the time it takes to understand its operation. We will start by checking the seals while the slide is retracted. Understand the mechanism that extends and retracts the slide. We will operate it several times and understand the restrictions like where the drivers’ seat has to be for proper clearance. Understand the interlocks that might be present, like some systems don’t work if the compartment below the slide has a door open, etc. Understand the manual retraction process and actually perform the retraction as if the automatic mechanism had failed. We will look for proper alignment of any wheels that may ride on carpet or other flooring, to insure proper clearance. Understand any locking mechanisms that are used to hold the top of the slide out tight against the top of the RV. We will do your best to make sure the seals are properly installed and operational when the slide is retracted and also when it is extended. Now its time to go inside. Cabinets — Together we will inspect all of the cabinets to insure that all the hinges and latches work well. Next we will pull each drawer out to its stop, return it closed and then try to open it like road vibration might do. We will make sure that there are no water leaks and that all the wiring and pipes are well fastened. We will inspect the linings, which are usually carpet, to insure they are fastened securely. Lighting — We will operate every light switch and observe its function. There are also battery disconnect switches to understand and verify. Closets — Next we will open and close all closet doors checking for free operation and proper alignment. Hanger rods should be properly fastened and secure. We will check out the lighting that is provided and any switches that are used. Furniture — We will examine every piece of furniture to check for construction, upholstery, pattern and cloth matching. Check out the dinette by making it a bed with the appropriate cushions. We will look closely at the quality of the driver and passenger chairs, since most of your time is going to be spent there. We will inspect and understand the operation of the safety belts. Locate any other seat belts in the couch or chairs. Blinds — We will operate each blind and check for alignment. Look at all valances and trim to be sure it is secured. Check out the pull drapes that usually cover the windshield by opening and closing them. Counter Tops — We will inspect all counter tops for alignment and fastening. Make sure that any trim pieces that should be there are in fact tight. Check for caulking quality everywhere there may be water. Check the installation of sinks and faucets. Windows — We will open and close every window and operate the locks. We will pay particular attention to the two safety egress windows or emergency windows and make sure they operate. Locks and latches should work freely but securely. Floor Coverings — We will inspect carpet and other floor coverings in all corners to insure that they have been properly fastened down. If tile is used we will inspect the grout to insure that it is complete and has been cleaned up properly, especially under any sliding cabinets. Wall Coverings — We will check to make sure that all the wall coverings actually cover and join properly. Operation Test of all House Systems Now together we are ready to test all of the house type systems. We will start this test with the RV not connected to any shore facilities. Generator — You will learn how to start the generator and stop it. Know where the remote stations for this purpose are located and how they work. Start the generator listening for any unusual sound or vibration. We will let the generator run a few minutes and understand any Power Relays that might be in your RV and test incoming ac electricity before cutting it through. The electrical status panel should show the status of the generator and the presence of ac voltage. We will put a load on the generator by starting the microwave and operating it for several minutes. Turn on and off all ac loads like the lighting that is not dc powered. Inverter/Converter/Charger — With the generator running, understand the operation of the Inverter/Charger that is provided. We will explain the function of each control switch, display and status light. With ac power present, the inverter becomes a charger and should be charging your house batteries. You can verify this by looking at the display. Now shut down the generator with the inverter in the "on" position and the ac loads should immediately be taken over by the inverter. We will again operate the microwave for a minute to test the inverter. The 1000 watts of the microwave will provide a good test load for the inverter. Now we will turn on a TV to create a small load on the inverter and leave the TV on during the rest of your House Systems Test. Please read our Converters page for more information. Water Pump — We will fill you fresh water tanks, so now we can test the function of the water pump. After turning it on, we will hear it pump for several seconds, even up to a minute to create enough pressure in the system. We will run water in the kitchen and bathroom sink and notice that the pump will come back on until proper water pressure is restored. Please read our Plumbing page for more information. Water Heater — We will try the water heater on propane first. A few seconds after we will turn it on, you should hear the click of the igniter and the small pop when the burner lights. The red light should stay on until that process happens. Now we will try it on ac. This is not normally done with no shore or generator power, but it is a good way to see if it works, because you should see an immediate dimming of dc lights because the battery is being drawn down with the inverter providing ac power to the water heater. Please read our Water page for more information. Furnace — Now its time to understand the operation of the thermostat that controls heating and sometimes air conditioning. We will turn the furnace on and set a temperature demand that is at least 10 degrees hotter than ambient temperature. In about 30 seconds, you should hear the furnace fans come on. Shortly thereafter you should hear the click of the igniter and the sound of the burner. We will let the furnace blow and you should get hot air at about 110 degrees coming out of all vents. Check each one. Now we will turn the furnace down and the hot air will gradually turn cooler and the fans will eventually stop after the furnace has cooled sufficiently. During this process have your smeller working for any smell of material getting too hot, or exhaust coming out. Please read our Furnace page for more information. Propane and Carbon Monoxide Alarms — Before you separt we will check the function of these alarms. Please read our Fuel, Oil & Propane page for more information. Refrigerator — Most modern refrigerators work on Propane and AC, or have an automatic mode that gives preference to ac and then will switch to propane if ac is not available. Understand the controls and the status lights and set the unit on propane. We will go outside and make sure that the propane heating column is lit and heating. The refrigerator needs solid 12 dc to operate. We will set the temperature at the highest cooling setting, because setting it to lowest will typically cause the coils to collect moisture and ice up. You will come back in about 10 minutes to feel that the coil is actually starting to cool. Please read our Appliances page for more information. TV VCR Antenna and Switching - Satellite Dish — Your front TV should still be on testing the ability of the inverter to provide constant ac power. We will review and understand the switching system that allows the selection of viewing channel on the front and rear TV. We will raise the TV uhf/vhf antenna and learn how to turn on the amplifier. Activate the control on the front TV that scans for local stations. Now you can learn how to rotate the antenna to maximize the quality of the picture. If you unit has a Satellite system, you'll learn about the complete operation and control of the antenna and receiver along with any switches. Learn how to make your system automatically acquire the proper satellite and how to use the DSS receiver Remote Control. It is also necessary to understand the video selection switch that distributes signals to the front and rear RV. Most receivers allow the remote to be used with IR (Infra-red) or RF (Radio Frequency). We will learn how to select the transmission method. Please read our Satellite Dish page for more information. Air Conditioners — Most air conditioners also have a heat strip or heat pump feature so now is the time to verify these functions. We will start the Generator verifying that your ac control system switches the ac power into the coach. This sometimes takes 90 seconds. The inverter should switch back to charging mode. When the generator is settled out and stable, then we will turn on the front air conditioner. After a couple of minutes, cool air, 20 degrees cooler than ambient, should be coming out of the registers. Leaving the front unit running, go back and turn on the unit in the bedroom. It should also cool in a couple of minutes to a level of 20 degrees below ambient. The generator should hold steady with this higher load of two units. Now we will switch both units to the heat strip or heat pump position and set the thermostats to require heat. Within 5 minutes warm air at least 20 degrees hotter than ambient should be coming out of the registers. If you coach has ducting in the ceiling, make sure a good airflow comes out of each register. Learn how to clean the filters at this time. Please read our Air Conditioner page for more information. Air Vents — We will test the operation of kitchen and bathroom air vents making sure they open and turn on properly. Then we will verify that they retract and close tightly. Microwave — With two AC’s and the microwave operating, you are near the maximum capability of a 7.5 KW generator. The generator should hold strong with this load. We will make sure there are not unusual sounds coming from the Microwave. Please read our Appliances page for more information. Propane Stove — We will turn on one burner of the stovetop while the AC’s and Microwave are running and the automatic igniters should cause a strong spark to light the burner. Turn on the other burners to verify that there is enough propane flow to operate the refrigerator, water heat and all the burners. If everything is OK, then turn off the burners on the stove. Sometimes the igniters interfere with the operation of the thermostats for the roof air. This is caused by improper routing of wiring where the ac too close to the dc, inside the kitchen cabinet. Now is the time to find this problem. If your unit has an oven, we will then verify its operation now. Please read our Appliances page for more information. We have now done a simple test of the major house systems and can shut everything off including the generator. Even if you shut down the generator first, everything should turn off without causing any problems. Please read our Driving a Caravan / RV page for more information. Now you are ready to do a basic operations test of the vehicle or motor part of you motorhome. You know that all operating pressures and levels are proper, because we performed this basic status check when we did the walk around. So you are ready to sit down in the driver’s seat and learn how the drive this great vehicle. Cockpit — We will adjust you seat and mirrors for a safe and comfortable position. If the seat has electric controls, learn the function of each button. If it has manual control, then do the same thing with the control levers. Adjust the rear view mirrors to reduce blind spots to the absolute minimum. You may need an assistant to be outside moving the mirrors that are not motorized. Learn how the controls work, if you have motorized mirrors. Adjust the steering wheel for proper orientation to you body. Instrumentation — Identify the function of each gauge and understand what the normal readings should be. Turn the ignition on, but don’t start the engine yet, so that you can see all of the status and warning lights that might illuminate when you are driving. Have the PDI person explain what each status light means, and what your action should be in response to its illumination. Turn on and adjust the rear view camera monitor. There are several buttons and controls on the monitor and you need to understand how to adjust it for day and night operation. Start the engine — Most modern diesel engines require waiting until a "Wait to Start" status light goes out. This delay gives the control system a chance to get fuel pressure and other things lined up so that the engine will start easily. Turn the ignition to the start position and crank the engine. It should start easily within 2 seconds and you should watch the oil pressure gauge to make sure that oil pressure is present with 1 second (maximum 3 seconds) of starting. If no oil pressure is present, immediately shut the engine down. With the engine operating, check to see that the voltage gauge on the dash is registering at least 13.2 volts, which verifies that the engine alternator is operating. Now check the air gauges if you have air brakes, and you should see a steady generation of air pressure that peaks at about 120 psi when you hear the air dryer in the engine compartment give out a psssst sound. There should be no warning lights illuminated on the dash at this time. Dash Air Conditioner and Heater Test — Turn on the Dash Air Conditioner and let it run while you are doing the following tests. With a thermometer verify that the cool air is at lease a 20 degrees under ambient temperature. After cooling is verified, then activate the Dash Hot air, waiting for the engine to heat the coolant so that you can verify heating. You can do this on your short test drive, which will happen in a few minutes. Please read our Air Conditioner page for more information. Air System Test — If your coach has air brakes and air suspension, you need to test several things before you drive the coach. Don’t let the PDI person tell you that it’s OK to drive! Here are the basics. A more comprehensive air system test is described in http://208.55.19.51/ArtAir.html on this web page. It should take no more than 5 minutes to generate 120 psi, if the unit started from little of no pressure. Please check our Brakes page for more information. With the emergency brake applied, in the up position, put the vehicle into drive with your foot on the brake pedal. Next remove your foot from the brake and the coach should not move even an inch. Apply a small pressure on the accelerator, up to about 1200 rpm on the tachometer, and the coach should not move. If it does, do not drive it one inch, because the emergency brakes don’t work. Shift into neutral and leave the engine operating. Press the brake pedal, repeatedly to deplete the air pressure in the tanks. Watch the air pressure gauge and when it reaches about 90 psi it should immediately start generating pressure again. Stop pressing the brake pedal and lightly press the accelerator (while in neutral) enough to get 1000-1200 rpm on the tachometer, and the pressure should be back up to 120 psi within less than one minute. If you don’t then there is something wrong with the air compressor. Shift into drive with you foot on the service brake, being sure there is 100 yards of driving space in front of you. Stop pressing the brake and apply enough pressure on the accelerator to cause the coach to speed up to 10 miles per hour and then immediately apply the brakes hard. The coach should stop immediately without sliding any wheel. If it does not stop sharply, do not drive this vehicle until the brakes are repaired. Now shut the engine off. Again press the brake pedal repeatedly to use air pressure while watching the pressure gauge(s). The pressure should go down to past 90 psi and before 60 psi an audible (low air pressure) audible alarm should sound, and the low air warning light should come on the dash. Keep depleting the air pressure by pressing the brake pedal and when you are down to 40 psi, stop. At this pressure, if you attempt to release the emergency brake by pressing the control knob down, it should pop right back up. This means the emergency brake is working properly. If you have air suspension, then have the PDI person explain the operation of this system completely. It uses the same air pressure to maintain the coach ride height. It should be possible to deplete the air pressure in the air bags so that the coach can be stored or parked at the lowest possible level. Some systems allow for changing the ride height while in motion, like getting through a steep driveway. Learn how this system works if you have it. If there is a tag axle that is controlled with air bags, then learn about the operation. If your coach has an air leveling system, then again have the PDI person explain the control panel. If your coach has a hydraulic leveling system, have the PDI person demonstrate and explain its operation. At this point you should actually level the coach as if you were parked in a camping spot preparing to spend the night. Hydraulic Brakes — If you coach has assisted hydraulic brakes, then you must test all of its functions. It is easy to do, since they work like most automobile brakes. The only extra thing to do is to test the operation of the emergency/parking brake. Do this test with space in front of the coach and on a flat surface. With the engine operating, apply the emergency brake, put it into drive and apply a small pressure on the accelerator. The coach should not move. Release the emergency brake, drive forward at 10 mph and press the service brakes hard. It should come to a complete stop immediately with screeching or pulling from to one side to the other. Please check our Brakes page for more information. Short test ride — Now that you have verified that you can stop this machine, you are ready to go on a short test drive. Have the PDI person outside to verify the operation of turn and brake lights before you start. As you drive out of the parking lot, verify that your mirrors are set correctly. Watch out for the wide swing of the rear of the coach since it is probably different from your past experience. This drive should be about 20 miles long and the PDI person should be your passenger. The most important thing to do during this test drive is to listen for any unusual sounds and feel for any vibrations. You should be comparing the handling and driving characteristics to the coach that you test-drove during your selection and purchase process. This is a good time to test the proper function of the Exhaust Brake, Retarder or Engine Brake if supplied. Also operate the windshield washer and wiper functions. Try the sun shields to make sure they are easy to position and then stay put. Instrumentation should show normal reading throughout the test, be sure to check the gauges often. Start with city street driving where there is little or no traffic. Perform several turns watching the mirrors closely to get the feel for where the coach is on the road. Read http://208.55.19.51/ArtSafe101.html http://208.55.19.51/ArtSafeDriving.html Elsewhere on this web page before you take this test-drive especially if you have little or no experience driving this size coach. Once you are comfortable with low speed maneuvering, head for an Interstate. This first entry is critical, so leave yourself lots of room, because you don’t know how this coach accelerates. As you enter, floor the accelerator and you should get a response of steady acceleration without any unusual sounds. Listen for any sounds that are not normal, like whines or grinds from under the coach, wind noise from the front door or slide out, flapping awnings, engine and transmission. Bring the speed up to merge safely into traffic and go the speed limit. Observe gauges for normal range of operation. Observe the steering effort necessary to keep the coach going straight. If it takes too much steering then the wheel alignment is probably not correct. Go at least two exits before turning around to return to the parking lot. During this test leave the rear view camera operating as an added rear view. By now, you will have a list of things that you feel need correcting, but it will be then the end of the day, so plan on camping at the factory or dealer lot for the night. This will give you a chance to further test the house functions. Prepare yourself waiting until these things are corrected and don’t be tempted by the PDI person to sign the acceptance paperwork just yet. You should "dry camp" in the parking lot the first night and not be tempted to hook up to shore utilities just yet. Bring enough kitchen equipment and food so that you can prepare an evening meal. There is no better way to test the living facilities than to actually use them. Don’t be tempted, since you’ve had a tough day to go out to eat. Batteries — the batteries should be fully charged and to verify the charge state use a simple hydrometer to test the specific gravity. This test will take no more than 5 minutes and you should be careful not to get any battery acid on you or your clothing. Fully charged batteries should read 1275 on the hydrometer. Most coaches are designed with enough battery capacity to dry camp at least one night without having to run the generator, even if you watch TV several hours and use the microwave for limited cooking. When you get up in the morning, retest the charge state and the hydrometer reading should be no lower than 1175, which is equivalent to about 30% charge. In the morning, start the generator or plug into shore power, to verify that the inverter goes directly into the bulk (highest) charge rate. If you have the gauge or a dc current meter, you should verify that 45 to 70 amps are going into the low batteries. It will take two or three hours at that rate to recharge the batteries and you will just get started when the technicians will want to take your coach for the day, to fix all the things that you have on your list. Please read our Battery page for more information. If it is really hot, then by all means connect to shore power so you can run the air conditioners, but when it cools down. Disconnect shore power so that you can test your batteries for the rest of the night. While you are camped it is a good time to read all the manuals that will have been provided by the PDI person. This will allow you to review all the knowledge you have from all the testing that you have done the first day. Ask the marketing people to give you a list of the things to see in the area, so that with you dingy you will be able to entertain yourself for the day. You can spend the day waiting in the customer area, but there’s only so much visiting you can do with the other customers that are there getting work done. Some sharing is valuable especially if you get reminded to test something that you forgot. At about 4:30 or so, the technicians will bring your coach back to the parking lot and you should then repeat the testing of the things that were on the "fix" list and dry camp for another night. If the house batteries are depleted, then you will have to plug into shore power or run the generator for a few hours. If you find more things to be corrected, more time will be required by the technicians on the third day to do those repairs. Acceptance — When you are satisfied that all systems are "go" then sign the acceptance papers that the PDI person will anxiously provide for you. Schedule your first return trip to the factory for about a week from now. You are now ready to take your "shake down" cruise. Shake Down Cruise — Select an interesting destination about 100 miles away for your maiden voyage. Actually use all the systems multiple times to try to detect and infant failures (electronic equipment fails at greater rates at the beginning of its life). At your destination with full hook ups, refill the fresh water tank, and run water into the gray tank to verify the gauge reading and that there are not leaks. Drain the gray water using the sever hoses. Do the same thing to the Black Water tank, and if you don’t want to wait for it to fill with the toilet running, then bring the water hose in and fill the tank through the toilet. Check the gauge for accuracy and for any leaks. Now is the time you want to find leaks if there are any. Drain the Black Water Tanks and camp using all the systems for the rest of the week. Go to a truck stop and refuel as you return to the factory or dealer, so that you can test the fuel fill rate. Fuel should go readily into the tank without sputtering back at you. If it sputters then the fuel tank is not properly vented. I also like to refill the propane tank, even though it will not take very much, just to test the refill procedure and the gauge. Tires and Wheels — Closely inspect the tires and wheels and understand the proper pressure. I like to verify the torque of the lug nuts or have the PDI person do it while I watch. Please read our Tires page for more information. Awnings — Extend and retract each awning paying particular attention to how the awning is locked in the retracted position. Make sure all springs, lock, supports work well and are properly aligned. Please read our Awnings page for ore information. Put on some coveralls and get a creeper, which is a flat device with low wheels that allows you to lie on you back while scooting around under a vehicle. Drive the coach to a level place where it is safe to jack it up, blocking the tires, and then block up the chassis with axle stands so that it is safe to inspect the underneath. If you don’t want to do this then make arrangements to take the coach of a qualified independent truck shop and pay them one-hour labor to do this check. Inspect all air and or hydraulic lines, wiring, shock absorber attachments, and in general every place that a wire or pipe could rub against something that will cause a problem later. Look at exhaust pipe routing to make sure that nothing is going to get too hot from radiated heat when you are climbing that long grade on a hot day. Make sure the exhaust pipe is properly shielded from propane lines and tank. All wiring and piping should be properly fastened. Verify that undercoating has not been sprayed where it should not be, like on a brake caliper or filter sight glass. Check the operation of each wheel brake for proper adjustment and operation. Check for any fluid leakage. Understand how to check the operating levels of all fluids in the RV by actually checking them. Hydraulic, transmission, fuel, oil, coolant, etc should be included in this list. Understand the engine drive belts and how to inspect them. | |||||||
