tpms

Look at a TPMS as another RV insurance: you hope you never have to use it, but you'll be glad you have it if you need it.

I like the TST system, but it's the only one I've ever used. I'm not too crazy about the long lag time between sensor loss and notification of such. But I'm moved the monitor around in the cab and don't seem to be plagued with signal loss any more.

This question has been asked and answered numerous times in numerous threads.
I believe that TPMS will eventually save your fifth wheel from damage due to a blow out. I won;t leave home without it. I had it on my fifth wheel and it warned me of a blow out at least 3 times. I was able to stop and change the tire before it disintegrated and damaged my trailer.
I use TST and am very happy with it.

Brand? Does it matter as long as the one you select is capable of receiving signals from your trailera tires. People swear by them. But I personally would skip it unless I was towing with cheap ST tires.
