Which TPMS product for 3 axle trailer do you use/recommend?

I have a TST-507-rv-4 that works great. It came with 4 sensors but you can add as many as you need. The one I got has a monochromaic screen, guess they have color now so they can charge you more,, lol. It comes with a charging cord and one charge last many trips. Once you turn it on it takes about a minute to pickup all the tire sensors. It also comes with a signal booster that may be needed if you use it for the trailer tires, but I bet towing with a pickup truck you wouldn't need it. I just have them on the MH with the unit on the dash and it picks up the rear tires with no issues without the booster. One of the best gadgets I have!

I used the EEZRV brand with my fifth wheel and dually. 10 tires total and it worked great. Even at 42', no need for a "repeater".

I got the tire minder. It's been fine and does what it is supposed to.
Monitors pressure and temperature.
I had to get a repeater for the trailer since the front of the motorhome was so far away. Just add more sensors for the extra axle.

EEZ RV brand here as well. Initial setup is easy and the peace of mind while towing, especially at night, is great! We’ve got 12 sensors total, 6 truck and 6 trailer. Buy cheap replacement batteries from Amazon and keep a few in the toolbox.

It’s probably the best investment in the entire racing operation.
