What size truck do i need to pull this fully loaded trailer?

For the weight of the total load given I would say any truck that's a 2500 heavy duty, the manual transmission is vary nice for towing, which gives you more control of the load. Tho you don't need a dully (a normal truck can handle the load), tho it is nice if you are towing anything above 25,000 pounds. Also dully's can not go off road too much (in rocky area's).
