Spent the last 6 days beating the crap out of it in the desert, then loaded it back up and towed the camp trailer home today. On the way down with the 4 wheeler, gas, and 50 gallons of water in the bed pulling the loaded trailer 80 on the hwy, I averaged 12.5 mpg. On the way home, loaded the same without the water, but with a ~25 mph headwind, I averaged 10 mpg at 80. This truck pulls the camper better than my Silverado 2500 did by a long shot.
Truck did well in the desert as well, it took a major beating with no issues aside from the multitude of brush scratches. Hell, I think some of the scratches even have scratches. It was dark tonight, but I will try to get pics tomorrow.
