Found they released the specs for the new Sierra HD. Looks pretty nice!

they look good but disappointed that you can't get the new 6.2L. the 6.0 is decent but kinda of a dog especially if your pulling a trailer. I was getting my 12 dmax serviced and was bsing with the service and sales managers. they said that they were told that gm might be putting a "new" updated duramax in for 2015 without def and huge hp/ torque #s like 450/875?? this was in mid September so I guess they were incorrect. I personally don't mind the def other than the crappy place you have to fill it
I don't see a difference??The HD's look good. Not a big fan of the 1/2 tons
Have you seen, sat in a new 2014/15? I was invited to the open house to check them out. They are pretty nice!.... No point in going Eco boost when the GMC's have a heavier tow rating and get better fuel economy. ;-) IMOEcoboost is the way to go! IMO
