New to the Site and travel trailers

Aww, come on. Don't give up so easy. Do you know what capacity torsion bars are on you hitch. They come in several different strengths. The highest capacity bars I have seen are 1400#. That truck and those bars should do an adequate job of supporting that trailer. You might also look at getting a set of stable loads for the overload springs; they help a lot. Good shocks also make a big difference. No matter what reasonable size truck you get, inadequate hitch equipment will give a less than optimal towing experience. Hang in there, it won't cost a fortune to make some basic upgrades, and could improve handling significantly.
