Question about TPMS and valve stems
I'm researching a new TPMS system for my MH and new toad (TST, Doran, Pressure Pro, TireMinder) and I'm concerned about the effect of sensors on the valve stems. Both TST and Pressure Pro say you need...

I bought an inexpensive TPMS on Amazon for my 2011 Jeep Wrangler when towing it behind my RV. My Jeep does have it's own TPMS as required by the Feds. I also have the stock rubber stems on my Jeep tires. Have used the screw on TPMS caps for a couple years now without any problems. Even towed the Jeep to Alaska and back with it. On one recent trip I did have a puncture on one of the Jeep tires and my screw-on TPMS alerted me in the RV immediately.
The only real issue I've had with it is the batteries needed to be replaced in the screw-on sensors and the only indication I had were some false readings on tire pressures. The batteries did cost me about $20 and I replaced them all at the same time. No other problems since, other than the one flat tire it detected for me.
Now, on the subject of steel stems: I also bought a Tire Minder system for my RV since it doesn't have a factory installed TPMS. (Sprinter 3500 DRW doesn't fall under the legal requirement.) The Sprinter came with rubber stems and the TPMS system uses screw on caps. According to the folks at Tire Minder that shouldn't be a problem. On my last trip out it wasn't and the system worked just fine. However, on the trip back I kept getting false readings and lo tire pressure alarms on two of the tires (both rear, same side). I don't believe it was an issue with batteries as they were all factory fresh and recently installed. As a result I've removed the TPMS caps from my RV tires and won't be re-installing them until I replace the rubber valve stems with steel ones.
