I was on the fence too, but soon as the first round of ordering started to have backorders i jumped to tireminder.
Outstanding Brutal, thanks!It's been posted several times through the thread and initially summarized by @thestuarts here.
Since we can't seem to get the OP or a mod to post the part numbers in the first post, here they are again:
PARTS REQUIRED TO ADD TTPMS to 2019+ RAM HD TRUCKS
TTPMS bumper receiver: 68375990AC (Avg cost ~$70)
TIM headliner module: 68404893AB (Avg cost ~$70)
TIM Pigtail cable: 68412666aa (Avg cost ~$9)
The kit for the TPMS sensors (4) for trailer wheels is 68433188AA (best price I've seen posted not too far back in the thread @ $146)
Most of these parts are currently out of stock everywhere thanks to this thread.
You will need to install the hard parts. @Phil T excellent instructions pdf here.
You will need to have the sales code option enabled by the dealer (unlikely) or use AlphaOBD, an ELM327 Bluetooth OBD2 reader, and a security bypass cable (KaodTECH recommended) to recode the BCM. There's a giant AlphOBD thread here.

For the 2019 trucks, you will need to use the Windows version and select the MY2020 under advanced - also thanks to @g00fy
He also suggested enabling "P/T chassis net: TTPM" Which I also did. Unsure if this matters but it didn't cause any problems I'm aware of. The TTPMS setup docs may indicate that this is necessary:
"The TTPM sends the information to the TIM via the Controller Area Network-Chassis (CAN-C) to be transmitted to the IPC."
TPMS (TIS) sensors for trailer (SOLVED - see 1st post) aka TTPMS - Trailer TPMS
Really need somebody who has the option from the factory to give us a log and their Vin so we can compare settings and find out exactly what extra hardware we need (if any). I also wonder if, like the brake controller, there's an extra controller box that's required and not showing in the...hdrams.com

I thought someone on here mentioned TTPMS wasn't available to order until Feb. Guess that's not true.
