By now all of us mega cab owners that live in HOT climates know that the mega cab AC is totally inadequate in hot (over 90 degrees) humid weather. Yes, we know you guys in Maine and Wisconsin don't have this problem, but if you live in AZ or TX or FL you know the problem.

I've heard rumors of a service bulletin on this. Anyone know about it?

 

Haven't heard anything about it yet, but I I am not messing with mine. I think my AC is just fine. It takes a few minutes longer to cool down than a vehicle with a smaller cabin or interior space, but mine cools just fine and I find myself turning the control to a lower fan setting because it gets a little to cold sometimes.
