TPMS Sensor Problem

[BJ SAMURAI]

Towing a fifth wheel. 4 sensors on truck, 4 on 5er. Right rear sensor on truck not registering, even after changing all batteries. Leaving on trip tomorrow. Until I can contact manufacturer for help/new sensor which sensor can I switch to protect all 4 truck tires? (Had blow out before got TPMS that did major damage to back of truck previously.) Should I switch with trailer left front or rear or trailer right front or rear? One side of rear near water tanks, other rear side near landing gear motor. Should it be one of the front trailer tires? Hope this isn't too confusing.
Thanks.

What brand of TPMS? Possibility that a signal booster might be required. Where is the readout display mounted? If it is mounted low in the cab, raising it might fix the problem. I had a similar problem with my EEZ unit… a booster fixed the problem.

It's EEZ. Been using for 2 years and haven't needed the booster. It's the battery that needs to be changed (changed them all). Just can't get the sensor open to change that one. I misspoke when I said the sensor wasn't registering.

TPMS Relearn Tool and if you are using any of your spares they do not have a tpms in the tire.
