Around 1999 both Ford and Chevy moved on to their newer big black v8's. Ford to the V10, which I have, and Chevy to the 8.1 with the Allison Transmission. I purchased a 2000 low mileage Holiday Rambler, installed the 5 Start tune and have been very pleased. The Chevy (Workhorse) combo may be a better power train, but I was scared off by all the brake and other issues they had. I can get my Ford worked on by almost any shop, although I have done all my own work so far. I did not want any of the problems that come with slides, so got a rig without them, but it's just my wife and I, that may not work for you. Lots of nice used rigs out there at great prices, good luck with your search.
