My buddy was traveling with his neighbor, who has one of those 40' DP's and a 400 HP engine. That motorhome is about 28,000 GVWR, so it a lot heavier than his gas motorhome with a 460" engine in it. He passes the DP on the hills all the time.
My 460" gas motorhome only has a factory 225 HP rating, much less than the 362 HP put into the V10, that can turn higher RPM's. It will go up the hills fine, and would be great on the east coast where there are no mountain passes at 9,700 feet, like found in California. BTW: My Bounder did fine at 9700' too, towing my Honda CRV up Tioga Pass.
Have fun camping!
Fred.
