Anyone know how I can pump up the towing capabilities on a Gladiator Rubicon with a 6 speed manual transmission? I understand it tows less than the automatic mainly due to the stress expected on the clutch. Would a heavy duty clutch solve the problem? Bought the truck and then was lucky to get a great deal on a boat, but the boat/trailer is 4600 pounds (not to mention people and gear) and the manual truck tows 4500. Would a heavy duty clutch get me closer to the 7000lb capability of the automatic?
