Seats in my 2020 Denali 3500 are garbage. GM took a HUGE step backwards in seat comfort. Previous two generation Denali's were some of the most comfortable truck seats I've ever owned. Personally hoping redesigned interior in 2023 (?) solve this problem. Denali should bring premium seating materials and comfort. Swing and a miss on this truck GM.

I'm a big fan of adaptive cruise. Agree with the OP on this topic, a bit annoyed that it's not available. Every vehicle we have has it, except for current GMC 3500 and soon to arrive 2020 3500 Denali. Even our Jeep Wrangler has adaptive. Will drive the 2020 until adaptive is released and trade - problem solved. Yes, a bit annoying, but GM will get there eventually. That could be a new marketing slogan. "We get there, eventually."

Honestly couldn't tell the difference in ride in the 15-19 3500 SRW vs 2500 (owned a few of them both). If the 2020's are very similar, not sure why you wouldn't get the 3500. Price is basically a wash...

Just took one home for a test fit. Denali 3500SRW Duramax on order, should be here in a few months. It clears the door by a few inches... Only have 1.5 inches in the front and 1.5 inches in the back. Backup camera for the win. IMG_1358.HEIC

Thanks! We are loving summertime here in Michigan. We have a house full of Mastercraft fans.

Almost 23,000 relatively trouble-free miles. Have experienced the following problems: Low coolant warning message - Leaking lower tube and three service trips to get "air bubble" out of the system Emmission code - required replacement of DEF tank (sensor problem in tank) Minor surging and slow speed drivability issues - resolved by ECM flash in November/December Love the power levels and lower noise from the L5P versus my previous LML's. Overall positive experience with this truck. Only two things I don't like: Regens - very noticeable (higher idle) and always a burning chemical smell if I come to a stop - drive thru's are the worst if you have a regen underway - have not raised issue to dealer Lack of some more modern features (heads-up display, push button start, active cruise, etc.) which should be resolved in next generation model Overall, I would buy this truck again.

17 3500 Denali Single Rear Wheel. Swapped out to 20" wheels w/275/65's.

Ran LT275/65R20 BFG KO2's on Factory Denali 20" wheels on my 2015.5 2500. Didn't touch a thing - no rubbing. Just purchased 2017 3500 Denali HD Duramax. Only come with 18" wheel from factory - moved to same 20" wheels as 2500 with same 275/65 but Michelin LTX Defender M/S. Same result. No rubbing, didn't touch keys, body or fender liners.
