F150 Diesel Ike Gauntlet

The truck going into limp mode after revving high on the downhill is likely an early production software glitch I'm guessing. Other than that, it seemed the truck performed well and as noted got good mileage. I watched the 2015 Ram Ecodiesel run the Ike towing a slightly lighter (7200 lb) and lower profile trailer and it ran a little faster and got a little better mpg than the diesel F150. So IMO the two are very close, and it's pretty pointless to compare them to the big boys or to the gas 150/1500s. The 3.5 EB or 5.7 Hemi will probably run much faster and burn much more fuel. Like others have been pointed out, the market for these trucks are for a daily driver that gets great mpg for such a big vehicle and also has the ability to tow a boat or midsize travel trailer.
