No complaints with this truck. This is my second 2500 HD Diesel in two years. My '04 I got all of my money back on trade for the '05. You can't beat the interior space,comfort and ride. I tow a 30' travel trailer weighing approx. 9500 lbs. loaded with ease.
I like the Duramax Diesel for power and improved fuel economy over gas engine. The grade braking feature is great on the Allison transmission. The electric extention camper mirrors are very convenient. Onstar and power lumbar/heated seats are nice comfort features. Great sound with Bose stereo/CD.
Would like to see more interior color choices and a larger sunroof opening. Needs more tire and wheel options.
