I was recently reading about the cooling system factory design changes that had to be made to allow the ~7000 lb tow capacity of the Gladiator. One change was the grill. It has slightly wider slots and a different mesh screen. The other change was the electric cooling fan. It was a higher CFM rated fan/motor. I think both of those changes can be made to our Wranglers. I'm not advocating anyone tow more than the rated tow capacity, just a mod that would give more cooling margin.
