Went to New Hamshire last week, towed 3000 lbs. about 350 miles one way, got 14.9 mpg, over head and hand calculation, that is about what i get around town towing about 1500 lbs half the time. This is driving very non agressive (lack of better words). Very impressed overall with this truck, it performed really well, especially up hills, tow haul mode is way better than i ever expected.
I,m towing the same load and weight this weekend to pennsylvania, about 175 miles one way, the only difference is that i installed the predator at 65 mode. Can't wait to tell you all about it when i get back
By the way just turned 12000 miles
