Just a data point for ya Bill.
The PO of my coach had installed the TST system and it came with the coach when I bought it. I like it fine......been in use about 6 years now. Flow thru sensors are on the duals and the only rub is that it took forever (or a little longer) to top them off thru those flow thrus using my old (nice and light) 100 psi pancake compressor. So I gave the little pancake to my grandson for bike tire air ups, etc and bought a 150 psi pancake compressor. The 150 psi unit performs very well (amazing difference, actually) .....just a little more weight though to count against my already "tight" GVWR.
Talked to the owner there at TST and he was not surprised. He said "You wouldn't believe how small that little air-up hole is inside the flow thrus." I'd buy the TST system if I were in the mkt, but there are others just as good, I believe.
Safe travels................. ed s
