Tire Pressure Monitoring System for Toad

Do the remote TPMS sensors work when attached to the valves on a vehicle that already has the factory TPMS system?

Any one of them should be fine. They don't care what the tires are on.

It's the same tire monitoring system as you'd have on your RV, just extra sensors to put on the Toad. Or if you only want them on the Toad, you just get the system with 4 sensors and then later, if you want to add to it for the RV, just do it.

I had the same thing happen where I had a front tire on my Jeep blow and I never knew it. I went about 10 miles before a passerby flagged me. Fortunately, it did no damage, not even to the rim. I think the tow bar and the three remaining wheels were enough to keep the Jeep balanced and the rim up enough to not even have damage to that. I know the distance, because on my way back a few hours later driving the Toad (I was dropping off my motorhome for some service) I saw my "road gators" laying on the freeway. I had not heard, anything, felt anything, and nothing was visible via the camera on the back the RV looking at the Jeep. That's when I got my first TPMS.

Frankly I have read good things about every system available. I went with the TST system because I looked at the site and saw the set up was super simple. Anyway I believe all the systems available will monitor the coach tires as well as toad providing you order enough sensors.
