Right, but the pockets _are_ meant to be opened, so it makes sense that you may want to cover them up again. I have to assume the right size cover exists out there somewhere...

I have a ‘21 Sierra HD that I had opened up the forward stake pockets for mounting a rack. Now I’m not using the rack and would like to cover up the pockets. Trying to search for the covers is a challenge because the market is flooded with the covers for the rear odd-shaped pockets that are uncovered from the factory. So it’s not an issue covering the rear pockets, but I can’t seem to find the right covers for the forward pockets. I measured the hole and it appears to be around 1.5” x 2.5”. From what I can tell, the pockets for the pre-2019 models are slightly wider, the covers are 1.75” wide, so I’m not sure they will fit. Anyone have any luck finding covers for the front pockets?

Yes it does! Attached some pics to show it since that was something I had trouble finding before I ordered mine. Tons of space when it’s flipped in the stow position, but still has a bit of clearance in the lowest drop position.

Another update for posterity: Parts already came in, scheduled to be installed next week. I again double checked when the guy called that everything would fit my dually. He went to the shop to check with the people there and everyone agreed that it should fit depending on how the 5th Wheel prep sits on the frame. I'll find out next week!

Quick update; I spoke with a guy at my local 4WheelParts today and put in an order for the Airlift 7500XL kit that should fit the truck. He said that theyve installed it on duallys before so it shouldn’t be an issue, and the website is usually too restrictive with the fit information. The compressor is on back order so I don’t know when it will actually be installed. I’ll update the post once I know more!

Hi all, I've been towing just fine for the past year with my 2021 3500 DRW without any modifications, but when I throw a ton of weight (literally) in the back or hitch it can get a bit bouncy. I had an Airlift 5000 kit on my previous Sierra 1500 and it was amazing for towing our heavy travel trailer (which was way too heavy for a 1500, which is part of what lead to the upgrade...). I looked into putting air on the new truck but its not clear whether anything will actually fit a DRW truck. The AirLift website says that the 7500 XL kits won't fit "commercial chassis" which isn't really specific, but might mean DRW. The 4WheelParts website specifically says the 7500 XL kit only fits SRW trucks. Since nearly every vehicle fitment search stops at "3500" and everything fits SRW, its impossible to really search for only DRW. And yes, I understand the irony of the 7500lb air bags not fitting the DRW... Anyone out there have any experience putting air suspension on a DRW truck and know specifically that certain kits will fit?

Tl;dr: Safelite put a new windshield in my 2021 3500 Denali w/ HUD and now the HUD is blurry. They insist it's the trucks problem because they used the right glass. I can see the glass part number and the stamp in corner says "HUD", but I'm not convinced its actually intended to be compatible with this truck. From what I've read from other people online with similar problems in other makes of cars, this is absolutely a windshield problem because the glass has to be specifically contoured to your make of HUD. I want to confirm for myself that this glass isn't compatible with the truck, but I'm finding it extremely difficult to find this information. I've tried to look up part compatibility on my own and apparently the auto glass industry keeps their inventory and compatibility a huge secret... I can't find a single website that will show you vendors or part numbers for compatible glass by VIN or make+model, just dozens and dozens of glass companies willing to replace my windshield sight unseen without telling me what they're replacing it with! Any suggestions for how to look up compatibility for the windshield they gave me _or_ find compatible windshields for my truck to compare? For the record, they put a Fuyao DW02500 on my truck. Oh, and the reason for the windshield is boring. Got a huge rock chip a few weeks ago, and with the cold nights recently a crack formed that covered the entire windshield side to side, and was becoming very disruptive to my FOV when driving. Wanted to get it fixed ASAP, and i'd never had a problem with the quick windshield places like Safelite before... but I guess with a newer car I need to be a lot more particular now.

So I’ve now had something similar happen. 2021 Denali 3500, we parked at a campsite yesterday and everything was fine. Today neither of our fobs work for remote lock/unlock, but we can use the physical handle buttons on the door, and keyless start does still work with the fob in my pocket. It’s dry and sunny today, and we did not just get any windows tinted! I like the theory that it has to do with the doors being open for a long time. It’s possible I left the doors open last night for a long time while I was unhitching the RV. In any case, I’ll update whether it fixes itself or if I need to take it to a dealer. I just wanted to add that this problem seems to occur without tinting

Yeah, that was the bulletin I used. What I mean is that I tried to order the indicated part number, but since they aren’t officially listed as compatible with my VIN it meant I would be penalized if I needed to return them. The return policy is usually different if you purchase with a verified VIN. Since none of the parts are officially listed I’m also a bit unsure whether these are the right parts for an HD or if those kits are just for the half tons, even though 153c makes it sound like they apply to the HDs too it isn’t super clear.

I can't speak for the trucks, but I had a 2016 Ford Fusion with push button start and it worked: You could get out with the key in your pocket and leave the car running. BUT... Fords honk at you if you do that. Not a chirp. Full on honk. I have no idea why. As far as I've been able to tell, they still do that, even the 2021s. Its such a stupid thing and one of the main dealbreakers for me to even consider getting a Ford. If I go out and start my truck in the morning and need to run back inside to grab something, I don't want it honking and waking up my kids/neighbors. Thats just ridiculous.

Hi All, has anyone successfully ordered parts for a 2021 GMC 3500? My truck did not have the upfitter switch option from the factory so I need to order the full kit including the switch panel and the knee panel for the dash. I found that none of the upfitter parts are listed as compatible for the 3500 model so it’s hard to figure out which ones are correct. I tried to order from gmpartsdirect but they gave me a hard time that they aren’t listed as compatible for my VIN. But then I noticed that as far as I can tell, GM hasn’t officially marked *any* parts as compatible with this model truck. When I search for parts for a 2021 GMC 3500 at gmpartsdirect the only pieces that show up are accessories / add-ons. None of the factory parts are listed for any part of the truck. Does anyone know what’s up with that? Many parts (including the upfitter switch) are listed for the Chevy 3500, it’s just GMC that’s missing, and I’d assume most parts are interchangeable.

Oh good point, I didn't consider that. In that case I may change out which one I order...

Thanks for the info! I totally agree, every truck is different. Plus it also depends on what you load into it... if you've got a huge toolbox + a bunch of equipment always hanging around in the back its going to sag a bit. FWIW in case anyone else discovers this thread and has the same question: It seems like I can expect the receiver height to sit somewhere in the mid-to-low 20"s. I ended up ordering the 10" drop hitch from weigh safe, I figured that will give me the most flexibility even if I don't need to use the full drop all the time.

If only a minivan could haul an 18,000 lb 5th wheel

Good call. I just checked a tire website to get the tire sizes from the factory. 2020 Silverado HC 2500 = LT275/65R20 = 275mm * .65 = 178.75mm = 7.08" tire + 20" wheel = ~27" overall 2020 Silverado HC DRW = LT253/80R17 = 253mm * .8 = 202.4mm = 7.96" tire + 17" wheel = ~25" overall So the DRW's axle is actually 1" lower to the ground. I imagine differences in suspension would raise the rest of the truck up to offset it, so they may be roughly the same overall ride height.
