Dar,

I think you are right, peoples views are colored by their past experiences. The idea that a modern 400 hp gas truck hauling a truck camper can go up an 8% grade at 65 on cruise control is just outside their experience.

Agree, gas engines have come along way and can produce lots of hp some have improved from a torque standpoint also. Torque is what is needed going up a 8% grade at 65 on the cruise control pulling a load, I imagine the 400 hp will do it however it will revving higher and shifting more often
