I bought my 2020 GMC Sierra 3500HD Denali Duramax CCSB off the dealer lot on January 7 and one of the options it had was the Snow Plow Prep Pkg, which includes the HD front suspension. I keep the tire pressures at 60 psi front / 80 psi rear and with the covid-19 restrictions I have only driven this truck about 2500 miles unloaded so far. The bottom line for me is this new truck rides as well as or even better than the 2013 GMC Sierra 1500 SLE extended cab I had previously. My best fuel economy so far with the Dmax/10 speed combo and sensible highway driving (60-65 MPH) is 23.8 MPG. I really love my new 3500HD truck and can see myself keeping it for a long time.

Thanks very much!

Love your new black 2500HD HC Duramax and was wondering if you'd be so kind as to post a pic of the weight sticker on the driver door jamb showing the actual payload and towing ratings for your truck. I'm undecided on ordering a 2500 or 3500 and would like to know the actual ratings for an HC rather than the ratings for a base truck on the Chevy website. TIA!!
