Depending on how much "stuff" you load in the camper, the average added to dry weight is usually considered to be about a 1,000 lbs. give or take. Granted, a TT does not tow as well as a 5er simply because all the tongue weight is at the rear of the truck. Add a weight-distributing hitch and maybe a sway control and you can come close.
One other thing you may or may not need is either air bags or overload springs depending on tongue weight.
