I just installed the Sykik TPMS on our Aria-all 6 wheels, and you can buy additional senders for your TOAD (something I planned to do after I made sure I'd be happy with the initial purchase).
Anyway, they seem accurate so far, from the storage bay to home and back. Once up to highway speed for a few miles, one signaled high pressure (by a couple of pounds) with a flashing screen showing the high pressure (122PSI) and an audible alarm beep. I'll adjust that one down before our vacation trip at EOM. The screen is small but that actually works in our MH because there is a small dead space in the middle of our gauge cluster-fit perfectly in there so I can see it as if looking at any other gauge.
