Most everything we buy for our RV we research and read reviews from Amazon and watch product videos on youtube to narrow down possible selections. No doubt accurate tire pressure and temperature are primary features for any TPMS, equally paramount is consistent connectivity to dedicated monitor or cellphone (via app) from valve stem mounted sensors, some may require a repeater be installed depending on distance from sensors to display.
Most TPMS have the same features, some monitors show tire info incremently while some show all tires at one time. Of course there are the major brands that tend to cost double the price of their less known competitors, whether they perform better and are worth the extra expenditure will be your call. We recently purchased six new 22.5" tires for our class A and picked up a 10 sensor TPMS with repeater on Amazon to monitor our $3K+ investment in rubber and Michelin tires on our toad.
