Any of the "Big Three" 3/4 ton diesels and matched transmissions will pull that 275 like it was a jon boat.Duramax, but I'm bias.
Rick, that Franklin Lock ramp was absolutely terrifying the first time I launched there! (actually, it was the first time I EVER launched my 225, we used that ramp. Back when I towed with the Exploder. I had visions of the truck slipping into the river.)
