which rear-end (pardon the expression) are you guys driving in the new 2015 F-150'2 and GM p/u trucks ? 3.73 or 4.10? All I can see on the GM website that is avail in the 2500HD is the 4.10, but I hear the 3.73 can be ordered. I had an old (1985,reliable) Chevy w/ the 4.10 rear end and the old 4 sp automatic. All it would get at 60mph was 10mpg. Empty, towing a boat, p/u camper with or without a boat in tow, air condit. on or off, summer or winter. I don't want to repeat that.
I tried, you can't order the 3:73 (well, last month anyway) for the 2500HD unless a diesel. But, I'm getting 10.5 mpg hauling my Truck Camper (3200 lbs) and about 16/17 mpg empty with the 6.0 gas and 4:10 and the 4x4 Dbl Cab Sht-bed.
My last GMC was 3:73 and 6.0L gas too, and got a little bit less, but not much difference between the two. I'm guessing the mileage gain in 2015 performance new in the older 3:73 is eaten up in the 4:10 RE, but it does climb hills better. So, it's a toss up, but if I could have done it, I'd have ordered the 3:73 again, and probably gained at least some mpg in the 2015 4x4 2500HD. The older 2003 4x4 6.0L - 3:73 hauled my camper just fine, hills and all.
