A RV is a massive vehicle that bounces down the road. It twists, turns and shimmies more than an automobile.  Many problems  happen in the electrical system because there is more electrical system for things to go wrong in.  Because of these things, RV preventive maintenance will save you money and grief down the road one day. 

I talked about the loose bolts in my air conditioner yesterday and how having that knowledge helped another RVer in the rain.  Between now an the next time you take you RV out maybe a few checks should be done.  You may know more than I do, but here are some I can think of at the moment:

• Look for rusted and corroded wiring connections and cleaning ground terminals will save your from many electrical problems later. 
• Inspect caulking around windows and basement doors. Are there large gaps or missing caulking. 
• Many leaks come from the roof.  Go up and look for gaps and cracks in old caulking, especially along the roof edge seams.
• Check your oil level.  Many engines have been ruined by low oil levels
• Change your oil and filter at the recommend mileage interval.  Dirty oil also ruins engines
• Change your generator oil and filter.
• Change the air filter on your engine and generator.
• Check your brake fluid level.  Do you even know where the reservoir is?  Mine is hidden in the driver wheel well, out of site and out of mind.
• Is the water/antifreeze level in your engine cooling system correct? 
• Inspect your tires for excessive wear and cracks. 
• Check your tire pressure regularly. 

This isn’t meant to be an all inclusive list of  preventive maintenance items.  It is meant to get you thinking about some things you may need to do to your RV.  When a car breaks down, you are often within 50 miles of home.  When an RV breaks down you may be a lot farther away.  Taking care of things today many prevent a breakdown tomorrow.
