We have never owned a TPMS for a coach. Most reason I have for this is we get new vehicles, 5, mostly pickup trucks or suv's every 2 - 3 years and that means 1 every year or more and we have never seen a TPMS on those vehicles that is not a problematic nuisance. At times and that is few they are accurate but if you look at the vehicle parked you will also always notice when the tires is very low. They even register a fault when all tires are at the same exact pressure! Never had a blow out on a truck or suv so maybe not best analysis for why not using a TPMS on coach.
This ought to be an interesting question. What system is the best TPMS for an 8 tire, 6 315's and 2 365's coach?
Am I correct in believing that if you have a blowout you will never be able to see it happening with a TPMS system. Lower tire pressure yes, that could lead to that, but not in the case of just a blowout from whatever reason.
This may shock some but my TPMS has always been the travelers going by me. And that has helped more than once over the years.
