We went to Camping World today and found the Truck System Technologies tire pressure monitoring system on sale for $299. It only included 6 sensors though and we will need to order 4 more for another $150. It was basically the same price as we could have gotten it through their website, but it was there at Camping World and we are planning another trip, so we went for it.
It was the one we had decided on after researching several different systems. The main thing that sold us on this was the fact that it not only monitors tire pressure, but temperature. If you should have a sticking caliper, which I hear is fairly common if the MH sits for a little while, then the temperature sensor will let you know before you have a problem. There are many things that can cause the temperature to rise and I would prefer to know about it as soon as possible.
Anyway, tomorrow I guess we will see how easy/hard it is to install. When we were coming back from our last trip, I wondered how long it would take us to realize it, if the toad had a flat tire! Hopefully, we won't have any blowouts or other problems, but it is just a little piece of mind.
We bought another little gadget at Camping World, but I'll go into that later.
