I have only had this truck for a week and I already love it. After filling up the first time I averaged 17.5 mpg. Thats better than my 5.3 Chevy not to mention the addition of a 4x4. It rides firm but not harsh. The only thing that would make a nice change is a nicer interior similar to dodge. The allison 6 speed electronic transmission... whew, when coming down steep grades the tranny holds speed to give the most secure feel . Going uphill the engine has enough torque to hold max gear and not shift down. So far so good.....
LTZ with the 6.0L Vortec and 8' box. Great engine; plenty of power. Sounds awesome. I am averaging 15 MPG in mixed driving (mostly highway) 6 speed automatic makes driving and towing easy. capacious cargo box. Very comfortable and plush interior. High quality materials instead of the hard plastics used in previous models. Were it up to her, my wife would be driving it instead of me.
Owning a 2010 2500 has been overall a Very nice experience. Having owned and F-250 prior to the Chevy I must say that the Chevy has had the upper hand from interior materials to turning radius and ride quality. Having bought the vortex 6.0 gas hasn't dissappointed in pulling power either. Would recommend for big truck owners
Truck constantly hunts for gears while going up a hill. I notified dealer immediately and they told me to let it break in. Notified GM and they said speak to the dealer. Dealer transmission guy plugged truck into computer and took it on a test drive and was able to experience the same issue. GM says that the vehicle is operating as designed! I guess the Toyota's were operating as designed too when the accelerators stuck and killed people! Poor design. GM needs to fix this. Do not buy this truck with a gas engine!
