I've tried TPMS with external sensors and they leaked too many times. I'm now interested in getting a system with internal sensors, and the September 2018 issue of Motorhome Magazine listed three systems.
Blu Technology Products has sensors that can be monitored with their smart phone app. I'm not sure I'd want to go that route because I'm afraid I'd need to take my eyes off the road for too long to see what was going on. There were a lot of questions that their website didn't answer. No information on sensor battery expected life, but they did have a neat system to stop sensor transmitting when the vehicle isn't moving.
Dill Air Controls has a set that has a small LED display for the dash that displays one wheel at a time every 5 seconds and has a good set of alarms for tire problems. The display isn't very large, but probably adequate. Their website was of very little use. No information about sensor battery expected life or whether the sensors stop transmitting when the vehicle is stopped.
Valor has a set with a display that shows one axle (up to four tires) pressure or temperature at a time with indicators to tell which axle is being displayed and whether temperature or pressure. Their website doesn't tell how often the display shifts, whether it shows temperature and pressure automatically or whether you need to use the toggle switch to choose which, etc. Sensor expected life is given as 5 to 7 years (which is time to replace tires), but no information about whether sensors stop transmitting when the vehicle is stopped.
I'm looking for anyone who has actual experience with any of these systems. Costs vary from $215 to $625, but my main concern is a quality product that works well in a motorhome environment.
