Pulling is NOT the problem....keeping tranny cool and suspension from bottoming out is. Also the small problem is stopping all that weight! Also would be nice to keep front wheels on the ground. I've seen tiny trucks hauling LARGE loads....they move it, but the steering was like going from no power steering to no effort at all!! Gee, if the driver could see his front wheels, like, in the air, he'd unload in a hurry!
