I was probably closer to 5500 and had a single axle trailer but did a lot of towing with my Dodge Ram 2500 6.7 Diesel with a Lance 830 Camper. I installed the torklift hitch with as I recall a 36" extension. The only complaint I ever had was sway but after installing the hellwig sway bar I was extremely happy. Never noticed a bounce at all and with the dual axle trailer I can't imagine you would. Didn't see what truck you had but I would absolutely recommend at least a 1 ton and possibly a dually and it must have a diesel. Don't do what many do and over camper your truck. It's no fun. As you point out it's going to hard going from the 5ver to a TC but they make some really nice ones now with popouts and you can go anywhere.
