I installed the TST TPMS 507 in my 2016 PowerStroke 6.7L F250 toy dump truck and 2018 Heartland Fuel 355. The system works great. Easy installation and installation was not difficult. Now that I'm towing my 16,000 pound toy dump truck, I'm more relaxed knowing that the air pressure and temperature in all of my tires are easy to control. A must for campers!
