Most duals can be checked with a "Dual Foot Tire Gauge": Tire Pressure Gauge by VALUE BRAND - Tire Repair by Zoro Tools Industrial Supplies
Have you tried one?

If a Dual Foot Gauge doesn't work, drive to a tire shop, have them check the pressure, watch them and buy a gauge like they use.

In addition to what Mel said, folks also buy kits that extend the inner wheel valve stem through outer wheel hole to be accessible for pressure check and filling. There are also systems that tie both tires together and automatically equalizes pressure in both but prevents both from going flat in failure of one tire.

I have been using such a kit for 10 years.
See: Link Cat's EyeŽ - Innovative Products for the Transporation Industry

Here's another: Dual Dynamics

I have been using CrossFires (Dual Dynamics) for about 18 months and I am very pleased with their functionality

Search for the "checking tire pressure" posting. There is discussion and pictures there of dually solid stem extenders in use.

The "sticker tire psi" is merely a suggestion/ballpark/guess by the coach maker.
To determine the actual psi necessary you must have your coach weighed and use the "tire inflation charts".

That sticker gives tire pressure for maximum carrying capacity of the RV with original tires. The only sure way to know what YOU need is to weigh the RV and get axle weights. Then look up tire inflation charts on the tire manufacturer's website. To put maximum sticker PSI in your tires can make ride harsh, reduce traction, and increase tire wear.

Dually solid stem extenders are actually new wheel valves and require the tire to be broke down from the rim to be installed in the wheel.

What you are talking about are actually "LONG VALVE STEMS", (which must be "installed in the wheel"), like these:
:
Not solid stem extenders!
------------------------------------------------------------------------------------

These are "solid valve stem EXTENDERS" (which screw ONTO the valve stems already installed in the wheels:


-----------------------------------------------------------------------------------

These are "flexible valve stem EXTENDERS, (which also screw ONTO the
valve stems already in the wheels):


-------------------------------------------------------------------------------------
