Question:
I have a dynamax dx3 with your tpms system in it. I need 2 more sensors for the rear tires. There are none for the inside duals. Can I add some to my trailer with this system?

Hey Tim. To add sensors to the TST TPMS for RVs item # TST-507-RV-4-C you were looking at you'll need the Brass Tire Sensors for TST TPMS - Qty 2 item # TST-507-RV-S2. These will work great for your inside duals.
You can add additional sensors to monitor your trailer's tires as well. They offer a 4-pack, which is item # TST-507-RV-S4.
What model TST TPMS do you have? You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.
