Brian,

The rear ride height control system supplies whatever pressure is required
to set the height. It varies from coach to coach and even side to side on a
coach.

Unfortunately I'm sitting in front of a computer in Sydney and Double
Trouble is in Humble, Texas or I'd provide what the gages in the manifolds
read for you.

Regards,
Rob M.

The right answer is "it depends".

How much are you carrying where? Are the torsion bars adjusted correctly?

Basically, I noticed that our Royale tended to want about four pounds more
on the driver side than the passenger side. The Onan was in the left rear,
of course, but the LP tank was amid-ship on the passenger side. The water
was at the rear, next came the black tank and then forward of it was the
gray tank. In front of those were the fuel tanks. The pressure could vary,
of course, depending on how full everything is plus the junk packed in the
MH and the people and where they're sitting.

See why I say "it depends". The leveling system compensates for a lot.

I've read that the OEM bags should be 85-90 psi at normal loading and ride height.

I have one borrowed OEM bag and one Southland bag. The OEM bag reads 85 psi.

Southland claims their bags run 12-15 psi lower for the same height. I can't measure my Southland bag presently, but I'll check as soon as I get the parts necessary to fix the damage that caused me to need the borrowed OEM bag in the first place. Should be here in a few days.

I find with a full water tank, my left air bag runs about 6 lbs less than the
right. Our water tank is right next to the propane tank on the right side.
