Review on Elikliv RV Trailer Tire Pressure Monitoring System with 6 TPMS Sensors, Repeater, and Real-time Alarm - LCD Display, Pressure (0~116PSI), Temperature (-104~185℉) by Eric Speers

I highly recommend checking tire pressures on every car. Not only do they extend the life of your tires, they also have an enormous safety factor in addition to the correct tire pressure. This TPMS is exactly what you need for a 6 tire truck or van. Supplied with locknuts to attach to the valve to somewhat deter theft of the sensors.
