I had pressure pro on my last bus, mostly so I would know if the toad had a issue. It certinally gives you piece of mind knowing all is ok. It does not replace the necessary walk around, thump and visual. The sensitivity of the pressure pro was very good, and was a good way to check pressure on all or any tire at any given time. I did purchase an use a repeater, I am sure Tom can guide you on that. I took the system with me to my current coach for my toad.
