I have owned this truck since 2006 and now have 56000 miles on it. The Duramax/Allison combo outshines the rest. I have hauled volleyball teams, 15000lbs 5th wheel up the Cascades, to work everyday and a multiple runs crosscounty and I smile everytime I start this truck up. Do I have complaints? One, the roof liner fit and finish leaves alot to be desired :( I have drove the rest and this is hands down the best. A Quiet diesel that can smoke the tires. I laugh when the Toyota boys try to pull something heavy up the mountains, they just don't have it. It will be the last truck I own.
Exterior body is great looking. I put on a aftermarket chrome bug guard, door handles, nerf bar and MKZ wheels. Steering wheel controls. Great leather seats for the long hauls. Duramax/Allison... nuff said.
The cloth roof liner does not sag but the fit around the molding is weak. Looks like GM cut corners where they could. Rearview camera. Lighted vanity mirror (for my wife).
Excellent drivability. This truck has more power than the comparable Ford or Dodge, better mileage, and is MUCH quieter! (I'm a Dodge man) Mileage varies from 22 (cruise at 55mph, no load) to 12 (90mph with truck loaded and 14,000lb trailer). Plently of room in the cab and a full length bed too! Only problem with the truck is the moonroof has stuck open 3 times and lots of wind noise when open. The moonroof cover is designed more like a screen - the sun sure gets hot at an angle that directly shines on driver. The original tires had sidewall integrity problems at 55K. Goodyear great with warranty issues. The fuel gage takes a while to show that the tank is actually full (10min - 1hour).
1. Steering wheel controls for everything. 2. More power stock than I need. 3. Unexpectedly, intimidation of other drivers with the size of my dually. 4. Just plain fun.
1. Put a light on the passenger side vanity mirror (for darn near $60K, I gotta keep momma happy) 2. Somewhere large enough to store flashlights in easy reach of the driver. 3. Lose the moonroof. (screen issue solved with dark window tint) 4. Underhood lights (at least 2) 5. Optional HUD
Best truck I have ever owned, period. Not sure what these other bad reviews are about? I have had no major problems. This truck pulls my 5th wheel better than anything on the road. Many Diesel magazines have given this truck its best in class award, and for good reason. Its a very comfortable truck to drive and loves to be hot rodded around. I'm at 45000 miles looking forward to many years of driving and towing with this. I added a Delco navigation unit plus a Delco 6 cd changer, it was well worth the price.
plush ride for a 1 ton truck, rides better than my wifes F150 !! DURAMAX and ALLISON, do I need to say more!
Navigation with rear camera should have been an option. Power extend towing mirrors would have been nice. I installed after market rims because GM's are the worst looking heavy duty rims out of the big three :(
Having driven this truck only a short distance, 2400 miles, problems are already evident. The worst being a diagnosis, from a blood sample test, of carbon monoxide poisoning due to cab infilteration. This is caused by the missfiring of the injection electronics package and the poor cab fit and finish allowing the engine exhaust to get into the cab unless the recirculate mode is used on the heating system. Recirculate is defeated by the controller which will not allow the recirculate mode to be engaged except on max ac. The engine has very poor throttle response and smokes excessively under heavy acceleration. The engine has a propensity to consume oil.
I would say the seats are the best feature except that the drivers seat cussion has started to collapse and has come loose from the front retainer.
I would try to purchase a better engine from an outside source. This one is junk!
Bought deisel truck for camper and boat. this truck goes over mountain passes like the load isn't there, 15,000lbs. I bought an aftermarket engine program to increase performance, and with this chip I get 20mpg empty, 15mpg with boat or camper, 13mpg with boat and camper. Programer takes 5 minutes and allows me to program for specific loads or to put it back to stock settings, recommend this. There has not been 1 problem with truck and have already put on 12,000 miles in the first 4 months. Very happy customer.
