Yup, find one with a floorplan you like and go for it. Yes, Diesels will cost you more but the ride is way better. Can't see much difference in longevity anymore. As mentioned above, the coachwork goes to pot way before the chassis. Seen plenty of ancient, leaking piles of junk (both gas and Diesel) with perfectly running drivetrains. If you have the money to spend, you will never regret the Diesel purchase but you don't have to spend that premium to get something you will enjoy for many years.
