2015 Ram 3500 Mega CAB towing capacity
The 2015 Ram 3500 Mega CAB is published in 6 configurations with a tow rating of 28,820 lb (heavy-duty fifth-wheel territory).
The table below lists every trim of the 2015 Ram 3500 Mega CAB with the engine, drivetrain, axle ratio, horsepower, torque, GVWR, curb weight, and payload that go with that trim's headline tow rating. Manufacturers often publish more than one tow figure per truck — a conventional bumper-hitch rating, a weight-distributing rating, and a gooseneck or fifth-wheel rating — so the highest number here is the maximum across all hitch classes the source carries for the trim.

How to interpret the headline tow figure
Tow figures this high require a gooseneck or fifth-wheel hitch installed in the bed of the truck, and a corresponding trailer setup. Conventional bumper-pull towing on the same vehicle is typically capped well below this number — usually under 15,000 lb. Always check the door-jamb sticker and owner's manual for the maximum permitted on each hitch class before hooking up.
