2016 Melbourne tire pressure...where did they hide the valve stems?!

[campaholix]

Bought it in October, brought it home, spent the next weekend in it before being winterized. Stupid warm weather has me piddling around the rig and realized I can't even see valve stems on the outer rims and no way to reach the inner rims stems.
What's the deal with this set up? Never seen anything like it. I've been considering buying a TPMS but now not sure how it would install.

Appreciate any feedback, suggestions, info.

Our old class A had valve stem extensions so it was easy to check the pressure of the inner tire. The motorhome already had them installed when we bought it used so I'm not sure of the cost. Sorry.

Roger that...my old class C had "regular" rims and stems that I put extensions on....but this one is weird. Thanks for the reply

The outer rim points in and the inner rim points out. Both are accessible with a dual head tire chuck. You can put an 135 degree extension on the outer and a straight ext on the inner. They are 180 degrees opposite of each other through the holes in the rim.

Best way is to buy the braided extension hoses for duals.

Here's a link to all the goodies.

It will be easier to find them if you take the simulators (hubcaps) off. Mercedes uses rubber stems for all the wheels and plastic extensions for the inner wheel. If you go the TPMS route or go with steel or heavier extensions you would be wise to replace the rubber Oem valve stems because they will eventually leak with the extra weight.

Well that explains it. Thanks for the info.
Is removal of the "simulators" (that's a new one on me) required to check pressure?

If you have long nimble fingers then no. It does make it easier.
