Two more monitors for my truck tires

Last spring I purchased the TPMS 507 system from TST for my trailer. Worked great all season. This spring, while discussing safety issues with my brother (who also tows a 5th wheel), I decided to add two more monitors for the rear wheels of my truck. Yes, I have tire pressure sensors from the factory - but they don't actively read out the pressure or give temperature readings. With the extreme weight of the trailer pin on the rear wheels of the truck, I feel safer monitoring my rear wheels along with the trailer tires.

TST was great at offering special pricing for the two additional monitors. Can say enough good things about the company.

When I bought my TPMS, I went ahead and got the 10 tire setup (4 on trailer, 6 on the dually). Our truck doesn't have a factory monitor (apparently not required or installed on one ton trucks) and it sure is nice to know what those inside duals are doing let alone the rest of the truck tires.
