I think they are good and I think they are needed. I like the Doran Pressure Pro that is sold here thru the rvupgrade site. As far as new valve stems go, it depends on what you got. The ones on my coach are metal, so no problem there. The rubber ones on my toad were alittle too long and possibly alittle too old for my liking, so I had new ones put on.

Been using the "Pressure Pro" system for about six months now. Initially installed only on the MH but will be buying four more sensors shortly to include the toad. The system has worked very well with only occasional times when a rear wheel will not report in. I am running with only the stock antenna and suspect I may need the aux antenna when the toad comes on-line. It is great to be cruising down the Hwy and at the push of a button,you can see exactly what each tire is doing. Highly recommend the "Pressure Pro" and they are nice people to deal with.
We use the Doran Pressure pro. Currenlly only on the MH, but have additional sensors for my trailer and plan to put them on. I like it as well, easy to monitor the tires, and check pressures before leaving. Only downside is having to disconnect if parked for extended perios, month or so.
