Well, he doesn't want to talk about torque, but as a point of comparison I have a 32K pound rig with a 330hp and 950 ft lbs of torque pulling a 4500# toad, and while I can outrun some loaded 18-wheelers on the hills I definitely wish I had more torque. For example, the 400 HP Cummins they put in similar rigs the next couple of years had 1200 ft lbs of torque. Wish I had that.
But in reality, I don't do a whole lot of mountain driving so for the small percentage of the time I labor up the hills it is not a big deal. I takes a pretty steep hill to slow me down below 45mph.
