    Anyone here want to bet money that the 2014 F150 will get at least a 300lb tow rating bump even if NOTHING is changed in their power train.

    Funny you mention that I saw a guy in a brand new f 150 platinum who attempted to two a decent sized excavator. I think my truck might have done it. But his axle u bolts snapped(I'm guessing) because his rear bumper was slammed into the ground. The truck was totaled for sure
