Some RV companies advertise that there products come equipped with TPMS. I just bought a new fifth wheel with that advertisement. The TPMS system consisted of 4 valve caps that showed green when good and red when low. The dealer when walking through said that as long as there's 80 lbs, the caps will show green. WRONG. I got it home and installed my TST system. They all four went into alarm reading 67 lbs. Moral to the story, don't trust the cheap caps.
The one I have (mentioned above) seems pretty accurate compared to my pressure gauge. So far, so good (~6 months). Having caps that change color would be better than nothing, but being able to constantly see what the pressure is WHILE driving is very important. It will also alarm if the tire pressure drops below a certain level. For me, it is a no-brainer safety add-on for less than $100.
Safe travels, and happy camping!
