My daughter purchased an inexpensive TPMS and I helped install it. The monitor worked from a nice distance from wheels, the small sensors have a replaceable battery. System costs $69 and comes with 4 sensors. Not sure how to buy more sensors. Might be cheaper to buy another package. I had no idea workable systems are available at these prices.

Max pressure [87 psi] might not work for me.
Pressure is too low and 8 meters won't do the trick. May buy one for our car though. All new cars are going to be required to have them. They sure do look slick.

It's right there in the same ad you linked. Extra sensors for $21.99

60 psi still too low for coaches.
Of course, but they come in many pressure settings. Designed for big trucks .

Both our cars have TPMS built in as well as the system on the coach. I also put those valve stem caps on that change color to red when the pressure falls below a certain point on Joyce's car. Now if she doesn't look at dash she might look at the wheels occasionally. :whistle:

Looking around at data, it would seem ideal if I could link the duals for pressure and have a TPMS alarm on each corner.
You would only need one TPS for each corner that way, and not care which tire triggers the alarm .
Some have had the link between the two duals leak and flattened both tires while in storage. Most manufactures recommend replacing any tire that has gone flat with weight on it.

Won't let you know in the coach, but on a coach walk around, easy to see if any have lost pressure.

Cross fire. The Cats eye does about the same . The pressure balance stops with a leak .
Add this to the valve cap system and alll should be good. IMHO
