Found something unusual this week while installing TPMS.

Finally decided to purchase a TPMS for our 2014 36LA Open Road and discovered that the valve stem extensions on the inside rears have a different thread than a standard valve stem. All the valve stems have the same thread pattern and the sensors screw on without issue but the extensions on both inside rear tire have a different thread pitch. I had to purchase new valve stem extensions and the TPMS sensors fit perfectly on the new ones but would not screw on the factory extensions. The extensions are installed by Ford on the chassis and not by Tiffin but I found it unusual that the thread pitch is different. Anybody else had this problem.

That is strange. Mine went on all 6 RV tires with no problems.
