Question about TPMS

AND.....if the "tire changer" insists that both wheels MUST have the long valve stems like trucks do, so that the outer one sticks back inside the rim.....find a different tire shop.

There is absolutely NO GOOD REASON that the two wheels must have the same kind of stems. PUt a long one on the back that comes out through both wheels so you can get to it. Put a short one on the outside wheel so it is easy to get to.

Sure, next time you break down the tires, get a more user-friendly valve stem.

But, in the mean time:

In most cases, you can move the coach so the inner valve stem is at the 3:00 or 9:00 position and lying on the ground, reach in and install the sensor.

No, it isn't fun, but not something you need to do very often. And, IMO, better than adding an extension that gives you another place for a leak to occur.

When all else fails solicit the help of a double jointed small person to slid their hand in between the tires and screw that sensor on for you.

X2 above statements.

Valve extensions will leak and fail-- but now, you will have a TPMS to tell you that . Spend the extra time to get properly configured metal valve stems.

When you have your RV in for new tires, or in for service, discuss your needs with the shop and explain what you want. There is no need to have to struggle with the inside dual when there are so many different valve stems available. Using the right valve stem will allow you to install a TPMS sensor or just inflate your inside dual. DO NOT just accept it when a "mechanic" installs inaccessible valve stems on your wheels.
Here is a picture of just SOME of the different shapes that are available. There are many many more that will give you access WITHOUT valve stem extensions.
