Mr. Mark, does your Prevost conversion slide outs have the air/inflatable seals? I'm not sure if the King Air has that feature, but for some reason, I thought the Prevost slides have that. I'm guessing the entry door has the same inflatable feature? I would definitely appreciate that feature. How about Over the Road Air? I thought some conversions kept that feature, and some keep that feature. I know that most production coaches (some select few models may like Country Coach?) don't have that feature even available. Without deviating from the OP's question on the chassis differences, I would say it's night and day difference from the K3 and Prevost. I know many people call the large Class A motorhomes buses, but beyond the outer box "look", the true bus chassis is far superior in most aspects, and the price tag speaks for it. As for the discussions previously on Kevlar, I use Kevlar for work (making bulletproof teller areas for banks). I'm not sure what type Prevost uses, but the Kevlar panels I use are quite expensive and beyond comparable to fiberglass. Also, I thought Prevost has two different model types e.g Kevlar/fiberglass looking and the stainless steel. They have different model numbers is all I know. I think I have Prevost conversion envy, but only hope to someday afford a King Air.
