I've have several over the years. I am currently using TireMinder:
TireMinder A1A Tire Pressure Monitoring System (TPMS) with 6 Transmitters for RVs, MotorHomes, 5th Wheels, Motor Coaches and Trailers
I like the TireMinder because it doesn't constantly scroll through all the tires. It only shows an event if it needs your attention. I find the systems that scroll distracting.
Also, it's very compact.
However, I think you will be happy with almost any system.
