Confirm with your door-jamb sticker and owner's manual. Your exact truck's rating depends on cab, bed, drive, axle ratio, options and tires, and your boat's real weight depends on its engine, options, fuel and gear. When in doubt, weigh the rig at a CAT scale.

Trailer brake controller
Boat trailers over about 3,000 lb usually need working trailer brakes (check your state's law); an electric-over-hydraulic or electric setup needs a controller in the truck.
Class IV receiver hitch & ball mount
Match the ball mount drop to your trailer so the boat rides level; the hitch rating must cover the full loaded trailer.
