Look into a Pullrite hitch. They have 2 models depending on what tongue weight your pulling. I purchased a TT that had a 900lb dry tongue weight because it had the kitchen forward, needless to say, after it was loaded I was at the limit of the tongue weight of my hitch and was all over the road. You can't tell the difference in the ride between the Pullrite and a 5er because it places the weight just behind the rear axel and can swing 70-90deg. to either side of the truck. Only drawback is you have to find some place else to put your spare tire.
