I think that's one reason I got out of RVing. I could fix the small leaks, stuff like that, but when the furnace would stop working, or the front jack didn't go down, or the water pump quit (twice), there was always something. We had a lot of fun at times, but there were a lot of times I would be to upset on vacation trying to figure out how to fix something.
P.S. Correct, I don't know how to change my signature line. I still have the 2000 F-250 with 96K on it now. No RV...sold that 7 years ago. Oh, the dogs dead too.
