Customer Reviews
Bought a 2500HD AT4 to replace our Yukon to tow our 28ft long, 11ft tall, 6000 lb camper. Plenty of shoulder and leg room for our 3 kids & 2 dogs. First diesel HD truck, and a bit surprised at the highway (19-20 mpg) and towing (11-12) mileage. Both are improvements over the Yukon (17-18 & 8-9). The truck is a road trip machine. Steering, road feel, and ride quality are great. Love the HUD, lane keep assist seat & visual alert. Camera display in the rear view mirror is surprisingly helpful with changing lanes or backing up when you have 3 heads blocking the regular mirrors view. This truck is huge, and our running boards are on backorder (2 weeks and counting). Climbing in and out without them is getting to be a pain. This also is not something we take into the city. The turning radius, big doors and overall length doesn't mix well with tight parking lots and narrow streets. All the cameras help, but not so much as to make it the easy option. Hard to say a $70k truck is a great deal, but compared to $60-$65k for a 2yr & 20k miles used similarly equipped, or similar price for Ram or Ford... We think the 10spd, towing capacity, fuel mileage (thanks TFtruck for all the testing, ours appear to match), HUD, mirrors & cameras, and the towing tech gave us the right mix of features & value for how we use our truck.
