Tire Pressure Monitoring System RV/Trailer TPMS with Solar Charging

In this review the Masoll M13 Tire Pressure Monitoring System is presented as a practical TPMS for drivers who tow trailers or own trucks and RVs that need continuous, hands-off tire monitoring. The bottom line: it is best for people who want a simple, accurate 4-sensor kit that automatically calibrates and keeps the display charged via solar power. The display and sensors are easy to install, provide clear pressure readings up to 87 PSI, and do most of the setup work for you, so users who want peace of mind on long trips will appreciate it.

Key Features

• Wide vehicle compatibility: Designed for vehicles with four tires including sedans, SUVs, pick-up trucks, RVs and travel trailers under 38 ft, so it fits common towing and daily driving needs.
• Auto set alarm and calibration: Sensors learn the standard pressure as a reference and automatically alarm when pressure rises 25% or drops 15%, eliminating manual threshold setup.
• Solar charging and power saving: The monitor uses an energy efficient solar panel with overcharge protection and intelligent sleep/wake to maintain battery life for continuous monitoring.
• Accurate pressure measurement: Built-in pressure chip delivers readings from 0 to 87 PSI with about 1.5 PSI accuracy, helping maintain tire life and fuel economy.
• Clear LCD with auto backlight: High-definition color LCD automatically adjusts brightness for day and night and uses an anti-reflective design for readable numbers in varied light.

Who It's For

The Masoll M13 is ideal for RV owners, trailer tow drivers and truck owners who want an easy to install, automatic TPMS that keeps the monitor charged without wiring. It is particularly useful for travel trailers under 38 ft where the sensors can transmit reliably to the cab display.

Those towing very long trailers longer than 38 ft should consider adding a signal booster for reliable transmission, and buyers seeking integrated tire pressure solutions from the vehicle manufacturer or multi-axle trailer specific telemetry should look at specialized systems instead.

Pros & Cons

Pros

• Automatic pressure reference and calibration reduces setup time and user error.
• Solar charging plus auto sleep/wake keeps the display powered without frequent recharging.
• Accurate 0 to 87 PSI readings with clear, auto-adjusting LCD improve readability and confidence on the road.
• Sensors are simple to install and work well on trucks and trailers according to customer feedback.

Cons

• Transmission may require a recommended signal booster for trailers longer than 38 ft to ensure consistent reception.
• Some users report mixed impressions of brightness, indicating the display may be too bright or dim in certain conditions.

Our Verdict

The Masoll M13 TPMS is a sensible, value focused choice for drivers who tow trailers or use trucks and RVs and want an automatic, low maintenance way to monitor tire pressure. Its auto calibration, solar charging and clear LCD make it especially convenient for long trips, while the 0 to 87 PSI range and 1.5 PSI accuracy provide reliable protection and potential fuel and tire life benefits.

Frequently Asked Questions

Will this work on my travel trailer?
The system is designed for trailers under 38 ft; for longer trailers Masoll recommends a signal booster to improve transmission.

Do the sensors require manual threshold setup?
No, sensors auto set a reference pressure and alarm when pressure rises 25% or falls 15% from that reference.

How is the monitor powered?
The monitor uses a built-in solar panel with overcharge protection and intelligent sleep/wake to preserve battery life.
