Purchasing a low mileage, low use gas MH

Not a motorhome, but I once bought a Chev P-up that was about 9 years old and had around 12,000 miles on it. The guy used it to tow his 5th wheel and only drive it in the summer. It sat unused and un-started every winter for nine years. I never had more problems with any vehicle in my life and all the problems were caused by the lack of use. I can't even remember them all. Had to rebuild the tranny, replaced head gaskets, brake drums got out of round and had to be replaced, rebuilt the carb, and those are just the things I remember. There were other things. I ended up putting way more money into it than it was worth.
