First what year? I have one of those little 5.9 Cummins engines in a 38 ft. coach that has ben over every major pass and grade in the US. NO PROBLEM, You need to learn to drive any large coach it isn't like driving your car. Nothing sadder than watching some one with a 330hp and up coach that can't get over hills easily because they don't know how to drive.oldryder said:Rookie looking to buy. Occasionly see Cummins diesel. I know it's a good motor in a pick--up. Enough motor for a 35' winnebago.? Other comments?
Thx for advice.

Definitely. The Beaver I had had a max gross weight of 50,000 lbs and it had 525 HP. My current Ventana has a max gross weight of 36,400 and it has 360 HP, actually accelerating (and holding speed on grades) a little better than the Beaver did, both with the same Jeep toad.WILDEBILL308 said:I just want to add that the accepted benchmark is one HP per 100 pounds GCW (Gross Combined Weight which is weight of loaded coach and anything you are pulling). When some one starts bragging about having 500 hp ask what the Gross Combined Weight is. Some of the heavier coaches are close to 50,000lbs. They perform in much the same way as the lighter coaches with smaller engines. )

A Traveler said:This is a very common - and incorrect - perception. You need HORSEPOWER for hauling and pulling. As Gary said, torque and horsepower are linked, but the key number is the horsepower number, not the torque. 300 hp is 300 hp, whether it's being produced by a big diesel at 1,800 rpm or a small gas engine at 5,000 rpm.

If you have any questions just ask.

WILDEBILL308 said:"I have to say that on the high passes, with a 6% grade, it won't hold much more than 45 MPH."
What gear and what rpm? If you can't accelerate in a gear on a hill you need to down shift till you can. Then keep your rpm near peak hp.
