Does anyone know what this connector is used for in the bottom left corner? I believe that the two modules that I do have are the keyless entry and the trailer tpms.

I was looking for an alterative to the over priced trailer tpms sensors and found out that they appear to be the same sensors that the 2021 Camaro and Corvette use. I ran across them on shopchevyparts. According to the pictures the sensors have the same manufacturer model number ANATEL 015-16-8001, but they are $30 a piece there. They do not come with the nuts so that is another $3.75 per sensor. I do not know much about these, so please double check this information if you are going to order some. I also do not know if there is any programming that is different that would prevent these from working, or if the valve stems are different. I just noticed the same model number.

I saw on another forum that other 433mhz sensors work. Does anyone know if there is a way to test a third party sensor without having them installed in the tire? Can I try to pair them without putting them in the tire?

I assume that these will work with the trailer for pressure and temperature? I noticed that they are not the same model number and that the valve stems are rubber and not metal.

Thanks!

Got my '21 AT4 HD, but didn't get the trailer tpms sensors or camera. The dealer told me I could get the sensors for $50, but when I went to lick the truck up they said the sensors would be $150 for two (I need 4) I think I saw on this forum that someone found them online cheaper. Anyone find sensors cheaper that do the temp also? Did someone else find the camera cheaper? I have $100 in GM rewards, but I hope I can find them cheaper.

Where is the stock subwoofer that comes with the premium radio in the 2021 HDs? The Bose system with the Richbass. Just got my 21 AT4 gasser and love it, but the bass doesn't hit as hard as I expected. It sounds like most of the bass is coming from the speakers in the doors. It doesn't hot as hard as the stock Bose system in my '16 Volt or '02 Escalade. I kind of want to make sure they put it in! Any settings I need to change besides the obvious eq?

Does anyone know the height of the hitch on a 2021 AT4 HD, or I guess it would be the same on all of the HDs? I have a Hensley Arrow and will probably need to order a new hitch bar. I would like to go ahead and get it before the truck gets here.

Thanks. I went with gas and will be pulling 8k lbs travel trailer in the mountains. I was on the fence but couldn't convince myself to put down the extra $10k for the diesel. Hoping I didn't make a mistake.

I have been watching many reviews of gas vs diesel and they almost always bring up that diesels cost more to own. They do not go into much detail. What are some quick examples if you don't mind sharing.

Thanks! When I built mine I didn't see the option to add a towing package. I assume it would come with that hitch. I did some digging and think this is the model number: 84834293

What hitch does the 2021 Sierra 2500 come with? Is it the same on the AT4? My friend just got a 2021 Ford F250 and the hitch says it is rated for a max of 10,000 lbs! Ford says the truck is rated for something like 12,500 but then put at 10k hitch on it... I haven't got my AT4 yet, but was wondering if GM is up to the same stuff. My 02 Escalade hitch is rated for 12k eventhough the Escalade itself maxes at 8,500.

I do not have my truck yet, but try this. Go into the settings on the truck and turn the hotspot off, or delete the trucks network (ssid) from your phone. Now your phone shouldn't be able to connect to the truck via wifi. I think android auto just uses bluetooth so make sure you phone is paired to the truck via bluetooth and your hotspot via wifi. That should let you pull data from your hotspot and still use android auto on the truck.

Thanks! I tried it again with no luck, but then noticed that it kept switching me to the 2020. Was able to get it to stay on 2021 and it was only about $400 difference. Thanks!

Are you using the chat off of the main page? All I can get it the automated chat, so I do not even get the chance to ask for a code.

Is there a way to get these codes without having to call a dealership? I have tried the GM chat, but it will not give me the code. The chat just gives me a generic response.

I am getting two very different prices on two extremely similar trucks. I put in an order for an AT4 when everything is added to it msrp is $68,660. The dealer then gave me some discounts and it is now down to $64,800 before the unknown incentives when it gets here. The dealer told me that price should be close if not better than the educational discount. I found out, thanks to you guys, that there is a separate build and price website just for education. When I built a very similar truck on there the MSRP came out to $67,930 then on the site itself it immediately drops the price to $63,776 and says that it is the GMeducator price. Then it drops it by another $3,400 for total cash allowances to make the total $60,376! I know that the cash allowances can change when the truck gets here, the other build site will just give me $2,050 for cash allowances. The educator build site was different and only let me put a premium package on it, not premium plus, so I had to add everything else one by one. The only difference in the two trucks is that I couldn't add the power running boards to the educational one online. Even if I added that later it would just be like another $1,000 (I added $800 running boards to the educational one to try to make the price closer)

I got news today that mine is at 3000 with an expected production week of 4/26. How long does it usually take once it is in that production week?

When does GM usually release the details of the next model year, and when do they become available? I have put an order in for a 2021 AT4, but I am starting to wonder if I should wait. I have read so much random stuff online from the interior being restyled, the exterior being restyled, new engine, new trans...

I put in an order for a '21 2500 AT4 last week. I am currently pulling a 33' travel trailer with an '02 Cadillac Escalade with a Hinsley Arrow hitch. The Escalade has the 6.0L, but only 4 speed transmission. The 6.0L is a great engine I hope the 6.6L is as good. The Hinsley Arrow is an awesome hitch! You can drive next to a semi at 70 and not feel anything! I decided to go with gas 2500 because of the GCWR. A lot of times it is overlooked, but is a very important number! My Escalade has a GCWR of 14k lbs. By the time you add the weight of the trailer, the arrow hitch, stuff we put in the camper, me, my wife, dogs, gas etc. We are right at max. The Escalade is rated to tow 8500, but that is if nothing, including people, are in the Escalade. I had to load our luggage in the back of the TT to try to take some tongue weight off of it. Be careful with towing numbers they are WAY overrated especially the Fords. I had a buddy that got a '14 F150 EcoBoost and thought he could tow like 12k lbs, but after you do the math he would max out at 7.5k! I am also going to feel better with bigger brakes etc. We do not tow in the mountains right now because the Escalade would barely make it, and the ride back down would be scary. The Escalade is a decent tow vehicle if not going up mountains. I hope that the 6.6L with the 6 speed tows better. Never got to try it out, but bought anyway. Anyone coming from a 6.0L to 6.6L? How is the difference in towing? Also have an 02 Escalade in great mechanical shape for sale if anyone is interested lol!

I don't think that you would get more hp out of premium gas. The point in premium gas is that it burns at a higher temperature. Really tight engines need it so that the gas doesn't prematurely detonate (knocking sound you hear) from the higher cylinder temperature.

How big is your garage? It makes your at4 look small!

I agree that the you should buy a truck because of it's dependability and capability. I just can not figure out why there are so many people that think the F250 interior is better than the Sierra. It looks like a work truck to me. Cheapest materials they could find plastic everywhere... Oh well just wanted to see if I was crazy.

Thanks! Now I just have to find what the invoice is for the truck configuration I want. I can not find an AT4 anywhere close to me so the dealership changed an already placed order to fit what I want as long as I put a refundable deposit on it. It is a 2500 AT4, White, Premium Plus package, heavy duty front spring package, 5th wheel goose neck package, power running boards. MSRP 68,8660 quoted price 64,800. Price should include dealer and education discount. I was told military and education discounts can not stack together. Price does not include incentives. Sound good?

Thanks! Now I just have to find what the invoice is for the truck configuration I want. All I have seen so far is just a range that goes all the way from wt to Denali.
