I had a crewmax and loved it plenty of power. Drove to Richmond purchased my camper pulled it home and traded it for a 13 duramax the next week. 7 mpg was the best I could get on 33sI have an 07. I've towed everything from boats, skid steers, mini exs, and my tractor. It will tow just fine. Fuel mileage will suck though.
