I am upgrading from at TT to a 31ft Class C with a slide out. I am concerned about towing a 4500lb van with the MH. The dealer says (taken with a grain of salt!) it should be no problem but is not quick to offer specifics. My two concerns are 1.) How good is the ford V10 and pulling up to 20,000 of weight (van, tow dolly and MH) and 2.) how the heck will I be able to stop with all that weight behind me! Any advice would be greatly appreciated! TOM P.S. Why are Saturns such a popular "toad"?
