Update to valve stem issue. ordered a set from tireman people. Sounded like an old guy running a business out of his home, but friendly and knowledgeable. Set cost me $135 and had it within the week. Took the set down to les schwab, They had a bit of an attitude towards putting them in, probably because I didn't buy them there, but put them in anyways. Their biggest complaint was the area on my rims wasn't very side making torquing the stems down properly difficult. they did go on and leak checked ok. Added tpms system, and drove it home. 1 sensor wasn't reporting, haven't looked to see what the problem is yet, don't like working in the rain. I got the Tire-Safeguard
RV 6-Tire Flow-Through Sensor Tire Pressure Monitoring System (TPMS)
sensors are a bit big, but both screw on and have a set screw to prevent them from moving. hopefully a few thousand miles won't mess with them.
