Like I said no one really knows how much fuel these trucks use. FISH what you say now?
So as 4x4ord mentions the 10 speed would have not made any difference. Did y'all see how cool the trans runs? YUP just like mine nice and cool.
Did y'all see how well the truck keeps the truck at speed downhill with the cruise on as I have mentioned many times? Heck I was holding 35mph at 14% in second for miles at 33k combined.
Rear air heck yea I know how well it works and yes my 15's steering is like being on rails unloaded and at full RAWR of 9,750# with a combined 35k.
SAE Towing capacity is 3k higher than the other two.
So bottom line I will gladly take a truck that is a bit slower up the hill with a "True Medium Duty" engine and transmission that will do this day after day and WILL get me down the grade with ZERO brake applications and the BEST part COLD brakes!
