I love it, wish it got a bit better mileage, but on a truck this big you can't really do much about it. It has more than enough horse power for most any job. I love the way it looks. I think I might upgrade mine to a 2500 though.
Make the tailgate latch better. Improve options (such as stereo, or that Duramax Diesal. Just mainly more options all the way around)
