First of all, I have always used a TPMS (TST brand) on my RVs from the beginning and would not travel without one.
I looked into crossfire products after seeing them on some big rigs and talking to the drivers. They probably do increase tire life by 20%. The problem with that for RVers is that even as a full timer I will probably have around 60,000 miles on my tires when they are 5 or 6 years old, which would be the point I would be replacing them anyway.
I think for commercial applications where they may put 80,000 to 100,000 miles on a set of tires in 8 or 9 months then squeezing an extra 20% out would be worth it. To me spending the money to put the system on an RV would be a waste of money.
