As far as checking the pressure. You can pull a line off at the hub if you see what looks like a valve stem check it just like a tire. If not you’ll have to take the line off at the wheel.
You can have different pressure on a set of duals. I picked up a bolt on a outside tire and the inside didn’t lose air. -
Just unscrew one end of the autofill line then check pressure as normal.

The hub has 2 knurled fittings at 180°. If I unscrew one the hose has the place I can put the air gauge on but that's measuring the pressure coming out of the tire. There's no way to measure what's coming out of the hub.
And the tire is low....
Guess when suns up I'll go poke around a bit and see what I can find... -

There’s a valve under the trailer that supplies air to the system. Make sure it’s open.
Take a line off at the wheel and see if it’s the same as at the hub. -
