A DP is not better than a gasser. It's just a different MH. The DP has less engine noise for the driver but can be very loud for anyone riding in the rear. I recently went back to a gasser from two DP's. I get 8 mpg and that all I got with the DP's. It handles and rides very good even in hard winds. The percentage of depreciation between the two is close to the same. I'm very happy with my Canyon Star. It pulls the hills better than my DP'S did. No regrets not to mention a hundred grand less money. $50.00 less per fill up, same size tank. Maintenance cost is a fraction of a DP. A Dp will go over 500 k miles before rebuilding. I've seen reports of the V 10 Ford going 300 k without any engine problems. I doubt if many of us will ever put that kind of miles on our MH. The new 5 speed Ford trans was a huge improvement with engine braking. A DP is no better than a gas anymore than a Cadillac is better than a Chevy. Different vehicles for different wants and needs. Get what you want and enjoy the adventure.
