Don't know why. Towing a 5k flatbed, my Suburban would get right about 12mpg, towing half flat half hills at 60-65mph. This is what I would expect out of a new-ish gas motor. The LLY, towing the exact same load (to the pound), on the same terrain, at the same speed, just did 12.9 this past weekend. This is, to put it bluntly, pathetic.

He gets 19-20 unloaded. I get 16-17. He gets 13-14 towing a 26' enclosed with a pair of Spec Miatas (10k+lbs), I get 10-11 towing the same trailer with one less Miata. I didn't spend $10k to upgrade from the Suburban, just to turn around and spend another $2500 on a programmer, exhaust, intake, blahblahblah just to match the mileage of other trucks on the market.
Maybe I will just sell it. It's a real shame, too, since it's a nice truck, but I bought it to save money, not to spend it.
