6 Best RV TPMS For Long Trailers in 2026: A Practical RV Guide
RV TPMS options for long trailers and fifth wheels, from a B-Qtech solar kit with a repeater to GUTA, Liwogi and RVMATE kits, with signal notes.
By Hardcastle's RV Editors
10 min read6 products evaluated
Long trailers stretch signals, and the farther the rear tires are from the display, the more likely readings drop out. This shortlist favors kits that include a repeater or state a long range, and notes where a listing is silent about range.
None of these listings states a maximum trailer length, so none is rated for a specific one.

What Matters Before You Choose an RV TPM For Long Trailers
Key buying criteria so you get the right fit the first time.
Signal over distance
A long trailer can place rear sensors far from the display, and metal bodies weaken signals. A repeater or booster helps. B-Qtech includes one.
No stated trailer length
None of the listings states a maximum trailer length, so any length claim would be a guess. Test the system on your trailer. Ask the seller for range data.
Sensor count for long rigs
Long trailers often have three axles, which means six tires, and a tow vehicle adds more. Liwogi covers 12 and B-Qtech covers eight. Count before buying.
Psi ceiling (long-trailer)
RVMATE tops out at 87 psi, while B-Qtech states 199 and GUTA GT90 states 188. Heavy trailer tires need a higher ceiling. Check the sidewall.
Flow-through for easy air
B-Qtech and GUTA GT20 use flow-through sensors, which help when adding air on a long rig. They need metal stems. Check your stems.
