I just looked up the specs for that engine (they can be found here: http://www.cumminsdieselspecs.com/4bt.html). That sounds like an absolutely perfect size for the Grand Cherokee, 1/2 ton and Dakota size vehicles. With 265 ft pounds of torque it would still be a very capable towing vehicle for the average person. My jeep runs at about 230-235 ft pounds and does a dandy job for anything that I am doing. I WANT ONE.
