Review on 🚗 Vesafe Universal Solar TPMS - Wireless Tire Pressure Monitoring System with 4 DIY External Cap Sensors (0-6Bar/0-87Psi) - Real-time Display of 4 Tires' Pressure and Temperature - Gray Display by Harry Love

Okay so that says it's not expected to work on caravans (RVs). However, I thought I would give it a try. It works but it took almost 20 miles of freeway driving for all 4 sensors to be detected. The module is also a bit smaller than I expected, making reading while driving a bit difficult, but it works and the preset alarms work for over- or under-inflated tires as well.
