Before you get your RV out for another year, there are several things you need to do to have a trouble free RV season.
Here are some things to check for.
• Reinstall batteries if they were removed, or check the electrolyte levels of the batteries. Check the state of charge with either a voltmeter or a hydrometer.
• Inspect the inside of your unit for water damage and the outside for potential leaks. Open up all cabinets and check all corners. Check below all windows, around all roof vents, and ceiling lights. Any discoloration would be an indication of possible leaks.
Outside, look for cracks or openings in the caulking around side walls, roof.
• Check to see if you have propane in the coach container. Verify the last time your propane system was inspected and leak tested. This needs to be done by a RV technician at the minimum of every two years.
• Turn the propane on and then light up all the appliances allowing them to go through its full cycle. Before you light the water heater or try it on 120VAC it must have water in it. Lighting it without water in it could cause the gas valve/thermostat to fail. While your appliances are cycling on propane you can start to check all the 120 volt alternating current (VAC) components. Most coaches need a minimum of 30 amps service.
•If the unit was winterized get it ready for use by de-winterizing it. With the bypass for the water heater still in the bypass mode, connect a hose to your city water connection. Turn the water on and run the taps in the coach until you have no more coloring of the antifreeze. Run all the taps, flush the toilet and run water through both hot and cold. Once the water runs clear for all taps, and then you can turn the bypass into the normal mode. This will allow you to fill the hot water tank. Once the hot water tank is full of water, you can run it through the cycle on 120VAC and also with propane as a fuel.
• If you have a towed vehicle, hook it up and make sure that the hitch is working properly. Once you are hooked up you can connect your trailer lights up and verify that all lights work.
• On a motorized unit check all under hood fluid levels before you start the engine. Automatic transmission fluid level must be checked with the vehicle running and up to normal operating temperature.
• If the RV is equipped with slideouts make sure that they all open and close fully and are sealed in both the open and closed positions.
• Check the leveling sytem/jacks that they retract fully and move back to a support position. If your unit is equipped with awnings, make sure they all open and close and the condition of the fabric is good.
• Check the air pressure in all tires.This needs to be checked when the tires are cold and the pressure should be as recommended by the coach manufacturer.
