The truck in itself is wonderful. It uses way too much DEF fluid when pulling a trailer. The stiffer Springs in the rear are causing a rough ride with a trailer. Great power, love the camera system, love the handling, very quiet.

If you want to go from a 1/2 ton to a 3/4 ton for towing your larger than 30’ travel trailer, this is an excellent choice. The new 6.6 gas motor will give you convenience towing any bumper pull trailer. If pulling the heavier 5th wheel trailers you probably want to go with the diesel. This truck with the gas motor rides really nice towing and empty. Don’t expect 1/2 ton gas mileage. I’m getting around 15 -16mpg highway and 12-14 city. My last truck was a 2011 6.2 Ltz 1/2 ton some performance upgrades. Long tube headers ,cold air intake levelling kit and larger tires with 20”wheels. I was getting about the same gas mileage . But had to use premium gas. When towing my 30’ travel trailer the 2500 gets between 9&10mpg (based on a 1500 mile round trip) I have owned 7 gm trucks over the last 40 years, all purchased new except 2 that were low mileage. All gas V8s, and never had any motor or transmission problems. Towed boat,snowmobile,cargo,utility,tent ,horse and travel trailers over the years. Hopefully this helps anyone trying to decide if this is the right tow rig for you. Ps I worked on the line in gm Oshawa for 46 years,if you were wondering why all the gm trucks lol.
