Roman Duck Wow, that advice is totally counterintuitive from what I was thinking. I guess I understood that sitting around isn't great for an RV, but we have passed on other rv's because of the higher miles (this one only has a little over 40K) as my assumptions were that the standard Ford 460 or Chevy 454 gas engine from the 90's trucks are in these things and getting anything more than 100k out of them is the ultimate lottery. I understand that high miles on a Diesel wouldn't be something to worry about, but figured the gas engines were comparable. What is the average lifespan of one of these Ford 460's, Chevy 454's, and I guess I've seen a few V10 Triton's?
