Newmar Ventana LE Engine Specs?

Well when we were in Naples, Fl over the holidays the DW and I went up to North Trail RV and looked at the Newmar Ventana LE bath & 1/2, 38 foot, at 33 klbs. It has the Cummins B series 330 hp 660 lb. ft. torque rating. It is a nice coach for our money we want to spend, but I am concerned about the low hp and torque rating.

Does anyone have any experience with this engine? Thanks.

It's a good engine, but for a 33,000 lb coach, 330 hp is adequate but not extra. Are you sure the Ventana weighs that much by itself? Or is that the GVWR? My 40 foot American Tradition is 32,700 loaded for travel and 37,700 with the toad on the back. It is powered with a 370 hp Cummins ISL.

The rule of thumb is that 100 lb/hp is adequate. You will slow down somewhat on long steep grades with that much hp, but that is how most motorhomes are powered. It's a compromise between power and fuel economy.
