I'm asking because I am curious. While the senors codes will not have to be re-entered because you put them on a different trailers, as long as you put them on the same wheel locations, it sounds to me, and I could be wrong, like you are talking about having to change the alarm parameters because the FW & car hauler carry different air 110 vs 80. That is just a matter of changing the parameter alarm settings. It seems you have a good work around with your 2nd monitor but it is not mandatory if you have more than one trailer. Di
re-calibrating the sensors is a pita for me, cause you have to do them ALL, even the ones that didn't change. I bought a second monitor and sensors for all tires 4 FW, 4 trailer, 6 Dually . one monitor when using my FW and one when using my enclosed car hauler..
FW at 110lbs, car hauler at 80lbs..
I just use whichever monitor I need.
when I am away from whatever trailer, I turn off the trailer sensors in that monitor.
