2020 Sierra AT4 with Trailer TPMS?

Recommended Posts

Just curious the 2019 AT4 with Premium Package included the trailer TPMS sensors. The 2020 AT4 with Premium Package seems to include the system, but you need to buy the TPMS for $50. Can anyone confirm if they bought a 2020 AT4 with Premium Package that didn't come with the $50 sensors if you were able to add them after the fact? I know on the 2019 Silverados you had to order the trailer tire system with the sensors or you couldn't get it after the fact. I'm looking at a 2020 AT4 premium package but the dealer says it's a $50 option now to get the TPMS but it's a little foggy on info if you can order them after the fact.

My '20 AT4 did not come with the sensors. I was under the impression that the sensors were included like the '19s. I don't even remeber seeing an option to add the sensors on the dealer configurator. Time for a call to my dealer, as I want them for my travel trailer. What's the point of adding the module and not even a set of sensors to work with it. At the very least I want them at the $50 build in prIce.


We'll see.
