my uncle has a duramax and has a dyno dominator and a power pup on it with a shift kit and its getting 22mpg

 

Thanks guys for the input. I'm currently trying to sell my truck but I'm not going to give it away. If it doesn't sell, I'll probably go with the Radix.

 

Go with the Duramax. Less likely to break something else later like trans or rearend. Forced induction I'm sure is fun but it could cost you more later. Go look around in the drivetrain forum. I plan to get a DMax next year.

Just my .02

 

That what I've heard as well, with towing only dropping to 15 mpg or so.

 

holy cow

Price of diesel depends on where you live. In some areas it is cheaper than 89 octane gas.

 

thats nuts. i would like to see other peoples mileage with a set up like yours because that is more than i would have expected.

 

Remember this is on a cross country trip......It is pretty flat out your way

 

I smile every day !
