  1. Well just traded my 2018 for a 2020 both High Country Duramax. We camp with a 16,000 pound fifth wheel so tow often in the summer. The 2020 has the factory hitch with a curt 25k. First off had to move the hitch to the highest setting and it still touched the bed rail pulling in my driveway the old truck was close but didn’t touch. The truck pulls very smoothly and feels good in the road transmission shifts a lot smoother than the 2018 but when pulling hills in Vermont is noticeable less power. With the 2018 I could set Cruze control at 72 and it would maintain speed today I was not able to at all was down to 68 for a bit on a hill I could go 75 if I didn’t pay attention. Does not have the pulling power. Then after pulling hill I had to go down a 7% grade one mile long and stop at the bottom and found the exhaust brake way less effective. I am over all impressed with the truck and the way it rides handles and pulls with confidence but they have missed the mark when programming the transmission for towing. This is my fourth duramax and I work on these as my day job and feel they really have cut power while towing not sure if it is engine power or just they way it is delivered with the transmission but feels about the same as my 15 duramax maybe little less. Still a great truck
