In a few weeks I'll be picking up my last new diesel, Ram 2500 4x4 Laramie. My next TT and truck combo will be lighter and smaller, a 1/2 ton with a TT <5000. With what I tow I could have gone gas 6.4 but the diesel puts down the miles much easier over the hills. BTW, my present 03 Ram was built in Mexico and has been the best vehicle I have ever owned.
