I know this thread is a little old, but I researched this like crazy so I hope this will help some one else.
I bought these same ones off of ebay - 4 for about $115 and had Les Schwab install them for me ($35). Search ebay for the part number XY74 has above. They work great and show psi + temp in the GM advanced trailering app in the truck. The one thing to note is that I did not get the horn honk confirmation during setup, I had to let air out for 3-5 seconds and just assume it was detected (which it was). I then re-inflated all tires after the setup. I have a 2020 GMC Sierra 1500 SLT with max trailering package (nht) - crazy that they did not come with the truck, along with trailering mirrors...
