"Have the Duramax Diesel and I am impressed with its power everytime I hook up the trailer. The Allison tranny is 2nd to none. There is no end to the power. Aside from the that its the usual GM problems, 6 months in and problem with the electric widows switches, driver mirror shakes in the wind, wind noise from left side of windshield somehwere. Its hard to keep buying American when our Hondas (2) just keep running without repairs."
"This truck has tonz of power beautiful lines and great interior. That said. I have had some problems with towing. The DPF that they put in to pass emissions is a fall back when towing a load up a steep grade for a given period of time. The truck will often fall into what is refered to as a "limp mode" where the truck looses power and you your family and your camping trailer are stuck on the side of a busy interstate. That is the only part of the truck I dont like but they put it on all new trucks. Rather than buying a doge or a ford I would much rather have a chevy.. ;)"
