Battery-free TPMS
The latest vehicles use a TPMS system without any little batteries in the sensors - it relies on the centrifugal action for energy. Do any of the aftermarket TPMS systems for trailers use this tech...

What I would consider ideal would be an internal sensor that had a rechargeable battery that is charged by the centrifugal action of the tire and wheel.
Then the sensor would shut off when battery is low for times when tire and wheel are inactive for an extended time.
That way I could still check pressures each morning before I break camp.
