As I am going thru and creating my maintenance log for coach 385 I was checking the date codes on the tires.  I looked at the air valves for the tag tires and was a little perplexed.  Now that does not take much, but how am I easily supposed to check the pressure in the outside tire, and why do they run the Shrader valve back this way.  The cap does have a spring loaded center section, I am just not sure why.  New to pushers and Tag axles.  Also would like to get a TPS monitor unit.  So here are my questions:

What is needed to check pressure?  Is it just a double headed pressure gauge?  Of coarse I have a nice single headed one.
Do I read thru the spring loaded cap or remove the cap as normal.  Not sure if I can get my sausage fingers in the little hole that easily.
What TPS system will work with this set up as is, or does something need to be changed?
What is a air multiplier when filling tires up, to get over 110 PSI if needed?  Is there an alternative method.

YEAH, it's pretty goofy how those stems are installed.  It's done for protection, but what a PAIN!!

This TireMinder gauge is THE BEST quality I've found and does the job perfectly!

I went through a whole process, and made a series of videos covering the problems and solutions for this.

A couple notes:
1. EVERY piece of hardware you use, such as a 180º extensions, presents another opportunity for a leak!!
2. ANY TPMS sensor will cause an enormous amount of force and/or vibration which has stressed these "extensions" to the point of failure...sometimes being a major leak.
3. Using top grade extensions COMBINED WITH RUBBER STABLIZERS will greatly reduce the chance for fatigue failure.
4. Air Fitting sealant is a good insurance to reduce chances of leakage.

A truck tire shop can change all this out for, including rotating the stems in the direction you need.

Here's my video to cover this issue:
