Good strong reliable truck.
By Dave | on Monday, May 20, 2019
Very strong truck, it's the work truck package and rides a pretty rough which is understandable considering its a 3500. It is the best 4 wheel drive pickup I've ever owned. I use it for working in the Oil/Gas Fields of northwestern New Mexico and have yet to have any problems with it. I've had Fords in the past and while the engines in them are ok, the transmissions don't hold up for oilfield use, while I've never had an issue with the GM transmissions.… - 3.0
Not that bad but……
By cole | on Tuesday, March 11, 2025
Works ok as a daily driver, but when it comes to towing….. forget it. Towing a 15,000 pound trailer (it is rated for it) It started throwing codes on the freeway for the turbo, it went into limp mode causing us to have to limp off the freeway with a 15,000 pound trailer… Took it into the GM dealer and they gave us a new air filter, yet it did it again and again…… The interior isn’t that bad other than the seat heater stoped working and the piping came out of the leather.… - 5.0
