Truck System Technologies TST-770-RV-4-TC 770 Series RV TPMS with 4 Cap Sensors

The Truck System Technologies TST-770-RV-4-TC is a complete Tire Pressure Monitoring System (TPMS) designed specifically for RV and trailer applications. The 770 Series delivers real-time tire pressure and temperature readings directly to a large, easy-to-read color display, helping drivers detect dangerous tire conditions before they lead to blowouts or roadside failures.

This system includes 4 cap-style sensors that thread directly onto standard rubber or metal valve stems — no special valve stems required. The flow-through cap design allows tire inflation and deflation without sensor removal, making routine maintenance fast and convenient.

Key Features:

• 5-inch TST Wide Screen Color Display — large, vibrant screen for easy monitoring while driving
• 4 Cap Sensors — compatible with standard rubber or metal valve stems for RV and trailer use
• Audio and Visual Alerts — immediate warnings for low pressure, high pressure, rapid pressure loss, and high temperature conditions
• Flow-Through Cap Design — inflate or deflate tires without removing sensors
• Suction Cup Display Mount — flexible windshield or dash mounting for optimal visibility
• USB and 12-Volt Charging — versatile power options for any RV cab setup
• Two Installation Wrenches Included — for proper sensor torque and installation

The TST 770 Series TPMS is trusted by RV owners and full-time travelers for its reliability, ease of installation, and expandability. The system can be upgraded to monitor additional axles as your setup grows, making it a long-term investment in tire safety.
