Maintaining your RV or motor home is key to prolonging its life. Your RV was manufactured to move, custom-designed to face the rigors of life on the highway and routinely subjected to bounces, shimmies and shakes. And, while every seam is sealed, the move and flex of travel can cause cracks and voids. Once moisture gets into your RV, the safety and integrity of your “house” can go downhill in a hurry. You must maintain it to this purpose, even when it is sitting still.

Whatever make and model of RV you own, if you want your RV to be ready to roll when you are, routine maintenance is a necessity. With that in mind, here is a handy checklist of what needs to be regularly checked and professionally maintained.

Because all RVs are unique, be sure to consult Texas Country RV for the right times to check or service each of the following. Then write these intervals in the blanks next to each line item.

Diesel Motorhomes

If you are accustomed to a passenger car or even a gas RV, your first diesel service appointment may be a bit of a shock. Compared to a gas RV, your diesel may use double or quadruple the amount of oil (14 to 35 quarts). The filters are larger, and there are more of them. Plus, diesels generally have four batteries instead of two. But here’s the good news: While each service appointment is more expensive, diesel engines can run longer and harder without routine maintenance, so maintenance appointments are also less frequent.

______ Check or replace air filter gauge
______ Change engine oil and filter
______ Replace fuel filter
______ Lubricate slack adjuster
______ Check water separator
______ Check Aqua-Hot® system
______ Clean and flush outside radiator coils
______ Check or replace hydraulic filters

Gas Motorhomes

Engine service on a “gasser” will look and feel similar to maintenance on a passenger vehicle. Motorhomes use more oil than passenger vehicles, and the various filters are larger; but otherwise, your engine maintenance should include:

______ Change oil (up to 8 quarts)
______ Replace oil filter
______ Replace fuel filter
______ Replace air filter
______ Clean and flush outside radiator coils
