Buying a Motorhome not a mechanic

I have had 7 motorhomes over the years and only 1 was new. If you decide you want a different one (larger)you will take a big financial beating. There are many 1-2 year old units out there that somebody is selling because it was the wrong size or something else. Many of these are overpriced because people financed them and can't afford to sell them because they owe more than they are worth. I
started in 1969 with a TT and have campers, and 7 motorhomes from a 21' class C to 38' Mountain Aire.
