I agree. I am more interested in longevity & warranty coverage than additional performance. I’ve said here before that my bone stock ‘13 model dually has towed my 16,400 pound 5th wheel over every mountain pass in the western US & I don’t think I’ve ever had my foot to the floor.I tow a 15K 5th wheel, my stock truck doesn't even care it's back there. Pretty much set the cruise and go. Reliability has been excellent, I'm not messing with it.
