Don't count on better mileage from the diesel. They're more powerful and cleaner, but they use at least as much fuel as the gas match in the truck. The new GM 6.0 and 6 speed get better mileage than my '08 duramax. Towing 10k# might be a different story, but as it has been said, If you don't see a 9k# trailer once a week, buy a gas engine 3/4 ton. You may not be able to drive a toyota, but you can still tell your friends about how big your truck is.

A powerful diesel in a truck that can handle a 12-15k# trailer every day is a working man's truck. If the truck can't take 3000# payload but the engine can move a small town, it's not much good.

I bought the 3/4 ton and wish I had the 1-ton. Just me I guess, but I've got a 10k# trailer at least twice a week.
