We are on our 4th MH. First three were diesel and this last is a gas engine. I will say that I preferred the diesels but this gasser fits the handicap needs of my wife who has to use a mobility scooter to get around and we could not find a diesel anywhere in the country and didn't want the better part of a year to have one built. The gasser quality of the coach itself is much better than the last diesel we had.
My confidence in diesel power comes from the Freightliner chassis over the years and they just keep on running. The Damon Essence body was like piling pig poop on a Cadillac.
I don't care what you drive/camp in/ travel in or whatever. Your money, your rig and your business. If you ask for a comment, I'll tell you and if you need help I'll give it.
