"Also, guess what rpm a 4.10 Ram 3500 that is in 6th to get that good mileage when towing? The same rpm I am at in 5th with 3.42s. Who da thunk it....."
I loved my 3.42's in my 11 HO RAM DRW. Only issue was I had to take it easy on launch on grade. Fast forward my 15 has 4.10's and AISIN. Hind sight I should have bought the 3.42's with AISIN and towed in 5th same rpms I now do in 6th. The LOW starting gears in the AISIN would have made launching 36k a non issue and had another gear for better highway economy running solo.
