I purchased too pull our travel trailer. the old truck 2015 1500 struggled to keep up with highway speeds. This one pulls the trailer great no problem keeping up with Highway speeds. The only issue is the DEF requirements. about every thousand miles it takes a little more than a gallon to keep it topped off. Needs a better monitoring system. The diesel engine runs great and gets better fuel economy than the gas when pulling the trailer.

Pulling my camper is great. Pulling large travel trailer is a dream. Hardly know it's back there. Great mpg. Diesel is great. Empty I'm getting 23 mpg. Pulling getting 15 mpg. Previous truck getting 9 mph. Rides real good. 5k miles on it now. No issues so far. My 2018 GMC Sierra 2500 HD crew cab has been just awesome. 22000miles on it now. It's boss on the open road. Hills are no problem. Rolls up down hills with ease. Other trucks going by are in passing gear mode. I'm purring down the road. I'd buy it again.

Mine has been in the shop at least 2 times a year for the last 5 years Lots of emissions issues level switch for def tank failures and on coolant tank. Fuel problems with fuel system not coming on and problems with computer. After I purchased while still under factory warrenty dealer was so cheap the would not replace factory decals pealing off truck. GMC and chevy have become the garbage of the US auto market.
