One big thing is to not abuse the engine. The old 350 cid engine is a work horse but does have its limits. The ones that I have seen with trouble are the folks that expect the engine to run the thing at 70 plus mph all of the time. Best to slow it down and enjoy life.
Our old trailer has you beat....it is a few years older.
Hope you enjoy the RV.
