I just bought a new 21 Ram 3500 DRW 4x4 and am looking for a TC. I would love to find a Bigfoot 10.4 but nothing out there.
I was back and forth on the HO and 4:10 also and ended up with a non HO with the 68RFE Tradesman with upgraded radio, manual 4x4 shift, 5th wheel prep and 50 gal fuel tank. For my planned use I think this is the perfect truck.
I towed an 8k lb trailer to the Midwest and plenty of power and the 3:73 are great.
1750 rpm at 70 and 2000 at 80. 13 mpg if I stayed around 65 mph.
Empty at the same speed I’m getting around 16-18mpg.
I wound Not want the 4:10 in this truck and the 68 shifts a lot smoother than the Aisin.
LOVE the 50 gal tank, almost 900 miles not towing.
It does use more DEF than my 17. Towing 1600 miles and running empty for 2300 mi, I used about 8 gal.
Compared to my 04 HO with 4:10, this new truck rides like a Cadillac and much more power and comfort.
