I bought the below one on Amazon. I haven’t installed it yet but it appears to be the only thing available for TireLinc ready RVs. In the front storage of our RV there is a mount that is identical to the one that ships with this kit. Everything you need should be included. You’ll have to search Amazon with the info below I’m not sure how or if it’s allowed to post direct links.
Lippert Components - 2020106863 Tire LINC Tire Pressure and Temperature Monitoring System for RVs (TPMS) with Tire Sensors and Repeater.
There is nothing special about the Tire Linc Pre-wire. It's just a cheap docking base for the kit you buy. I actually bought the Tymate unit below and tapped into the 12V wiring behind the Tire Linc Dock for the repeater. It has worked great so far.
I bought the Lippert Tire LINC kit that just popped on the pre-mounted base -- and it has served me well so far. I had an old, unused iPhone 8 and downloaded the app on ir to keep an eye on pressure and temp while traveling. We took a 2,800 mi R/T to MN in June and this setup worked flawlessly.
I see other platforms that have a different approach with displays you can mount on your dash or windshield. Having the available iPhone for an alternative monitoring display was what made the Lippert work for us. I have the phone mounted on a special cup holder that lets me keep the display on constant view.

And it is wired to your pass though light circuit. When I redid my solar controllers, I removed it as I had already gone a different route.
