Gas vs Diesel--the Diesel coach will have air bags and a MUCH better ride--also unless you get a fairly new coach the gas models will be noisy in the front--a Diesel pusher is in the rear and very quiet--I tried both before buying my first one and no comparisons--went with Diesel I have a 2004 H.R. Imperial I am thinking of selling. When looking at motorhomes--check the woodwork etc--I can't believe some of the poor workmanship in some . My wife is very quality oriented and hasn't seen any coach to compare with the H.R. quality--unless you get into the big bucks--good luck in your search
