TireMinder i10 RV TPMS with 4 Transmitters

Yes. The kit includes the Rhino signal booster, which connects to the tow vehicle's 12V or 24V power and extends RF range to cover the trailer's rear axle. Multiple owners report reliable signal across fifth wheel and travel trailer combinations up to full-size RV lengths.

The 4 external transmitters use CR1632 3V coin cell batteries. They are user-replaceable · unscrew the cap, swap the cell, reinstall. No tire dismounting required.

The i10 display can monitor up to 10 tires simultaneously and stores profiles for up to 4 vehicles (40 tires total). It auto-swaps between front and rear vehicle displays during towing.

It has a dedicated 3.15-inch color LCD display unit with an internal rechargeable battery, not a phone app. The display mounts on the dash or windshield and shows PSI and temperature readings simultaneously.
