Gas Mileage of 2013 Trucks - Gas and Diesel Both Welcom

My 04 Ford Diesel just took a******on me, so I'm in the market for a new truck. 98% of the usage will be driving from home to work, and the rest will be towing a 5th wheel.

I loved the Diesel, but it is so hard to justify the cost or a new one, 8k more just to get diesel.

I don't want a debate, as that's happened 500 times, and I know the benefits already. But, I would like just numbers of the following:

Must be a 2013 Ford, Chevy, or GMC (I just don't like the Dodge's).

What do you get for mileage? I'm hoping to compare the 3/4 gas to diesel to ton to ton duely, everything.

Basically, I know I'll get less mileage for gas, but if it's is like 5 mpg less, then that's fine with me. If it's 15, then I'll reconsider.

I'm particulary interested in what ton duelly's gas.

So, just post your mileage, year, make, model, and anything pertinent (gear / axel ratio, 4x4, 4x2, towing, etc).

Thanks, and let's keep this as just an informational thread no debates!
