Just some tips for those still troubleshooting their TPMS connection if it doesn't work after following manual: 1. If you need the larger size TPMS, Nichols Manufacturing out of Phoenix makes an adapter kit. They are pricey, but they work! I first tried using some from NAPA, but they didn't fit my rim thickness. The Nichols Manufacturing ones worked perfectly. 2. If you are not able to get a signal using the air down method, buy the cheap tool on Amazon referenced in this thread. That worked for me, but only after completing the next steps: 3. I had to rotate each tire so that the valve stem faced forward. 4. And I had to back my truck up so that the rear was facing the trailer. I wasn't hooked up to the fifth wheel as we were staying in it. Didn't want to go through leveling, removing the tri-leg stand in the front etc. First, I tried pulling up next to the trailer but was facing opposite direction. Then it dawned on me that it may be directional. Not confirmed, but it only worked once I turned the truck around and backed up as close to the trailer as I could. You may have better results than me. I had another 5th wheel with this setup and it worked flawlessly using the air down method, but that trailer was 38 feet long. This one is 43 foot long.

Thanks a bunch. Not sure why I didn't think to look more closely at the part. 0 for 2.

So it finally happened after about 20 tows.... I forgot to unplug the 7 way in the bed when I disconnected from my 5th wheel. Doh! It pulled the portion out that goes into the bed. It goes back in, but it broke off one of the clips that holds it in. I've tried searching on some reputable GM part websites, but I can't find the exact part. This is for a 2020 3500 HD. Any help with locating that part would be appreciated. Thanks!

My horn never honks either. What you need to do is start the learning process on the trucks screen. Then go to the left front tire and let air out until the screen acknowledges up in the cab. It helps to have another person sit up in the cab and tell you when it goes green. Then you move on to the next tire in the order the screen tells you. If you do all of this and it still won't acknowledge after letting 10-15PSI out of the tire, you truck is either too far from your sensors or there is something wrong with either the sensor batteries or their compatibility. I did this with my truck hooked up to my 40 foot 5th wheel and had no issues with that distance. Good luck!

Looks like a nice setup! Please share final results once you are done!

Thanks, Ron! I'm trying to visualize the setup in the bed. If you get a chance sometime, please do share a pic of that! Thanks so much!

I used GM part 84152501 for my trailer and they are metal stems. They work great!

I did, but I suppose its possible to take all of your trailer tires off of the trailer and take them in. It was just much easier for me to take the whole rig in and set it up and make sure it all works there.

Just had my GM Trailer TPMS installed in my 40ft 5th wheel. Worked like a charm using the air down method. It never honked the truck horn, but it did place a check mark on the screen next to the tire being aired down and then moved to the next. I used GM Part number 84152501 for my setup. It's not the 2020 specific part number, but worked just fine.

Thank you very much! My 5th wheel is about the same length so glad to know it will work.

Looks great! When you hook it up to your truck again, can you snap a shot of how you handled it from front cap to bumper? Trying to visualize how that would work for turns.

You can, but with a 5h wheel, the bumper connection is a bad location for turning. It was set up more for bumper pulls, apparently.

Let us know how this goes. And if you get any pics, please share!

Great info and thank you. That explains the large loop hanging underneath the 5th wheel I was seeing on the youtube videos. That could prove difficult. If only GM had gone wireless! Furrion makes it work.

Great! Please do keep us informed! I have about a month until my next trip to figure this all out. Ha!

Excellent! Thank you. That would be useful! Now, does anyone know if the low threshold is adjustable? IE, can you change the threshold?

So it seems there is very little info out there yet about how people are using the integrated rear camera. Anyone have experience with it pulling a fifth wheel? I have a 40' 5th wheel and I wonder how good the factory system is, difficulty installing, etc. I think I found that the 2019 camera works for the 2020 ( 84580657 ) but not 100% certain. can't find the 2020 part number reference yet.

For anyone using the Trailer TPMS system, is there a way to set high/low limits custom to your trailer tire requirements for pressure and temp? If so, what happens if it hits that threshold? IE, a blowout etc. Is there an alarm or other alert?
