480 ft-lbs, an 8 speed, and a 12,560 pound tow rating looks like a nice improvement on the older Ecodiesel. Need payload and EPA ratings still, but it's supposed to be better than the last on the EPA side and it used to be 19 city, 27 highway, 22 combined for a 4wd. The Ford f150 diesel is 20 city, 25 highway, 22 combined for a 4wd, so it should be higher than the Ford as the last one was equal. Chevy hasn't released their numbers yet either but it is looking good too, but with under 10,000 pound tow rating.
Looks like you wouldn't go wrong with any of the 3, but I really like the Rebel with the air suspension. I wouldn't care if off-road package dropped that tow rating down around 10,000 pounds it would be plenty for me.
