Thank You UWSkier, I was towing this TT with a 1500, max tow, until afm started, and went up 2500hd. Big difference in towing especially with wind, but not sure on mountains yet.
Thank You No F-bdy Bs, lol no money pile here, just planning the future. Never had a diesel, but lots of friends that do, they love them for towing their fifthwheels. But, our current routine of small daily miles with Grandchildren is probably not ideal for the diesel engine.
