FYI… the upfitter parts for the 2025s (Denali Ultimate, and I'm assuming the Denali, AT4, and AT4X) will fit the 2024. I ordered the center console cup holder with the cutout for the switches and installed it and the fuse box today. I still need to route the main wire from the battery. I couldn't locate the mounting location for the fuse box, though, so I'll have to wait for the upfitter update for the Denali trims.

It doesn't take too many converter stalls to reach the 167-176 F temperature range. I drove around a bit and got my temp up to 145 F. Pulled in my garage and did 3 converter stalls (hold brake and keep RPM under 1500 for 10 seconds) to to reach 172.
My 2020 has payload of 3146.
I checked a 3500 AT4 online and its payload was 3740.
I wanted a 3500 long bed AT4....but could only find 2500 standard bed AT4 up here in AK. Max tongue weight on the 3500 was 3165 and my sticker has it at 2775.
I ordered the complete kit part number for my truck...84942073 and it came with everything. Just match up the part number with your interior color and whether you have push button or keyed ignition.
Mine leaked last winter....but I live in Alaska and it was -30s/-40s. Replaced the gear box then the replaced the pressure line and had it arctic modded by a shop up here, not the ones GM sells.
Mine is leaking from the other side. I also noticed the plastic trim piece on top of the window on the inside cracked in couple different spots. Dealership has a whole new back window on order for the crack and will properly seal it up. 2020 GMC 2500 AT4
