DS air bags not inflating fully

Wanted to cut some large diameter steel tubing to put between the H frame for safety after inflating the air bags to work under the coach.  Hit the "raise" button to inflate the bags fully to get a measurement.  However, the Drivers Side air bags do not inflate as high as the Passenger side.  Is there an adjustment?
BTW, I tried dumping the air, then re-inflating using the raise switch; still no go.

Fiddler,
There are 3 leveling valves on our coach, 1 in front for front end height, then the 2 in the rear are for each side height, so with the coach raising but not all bags going up, it would apear the left (driver side) valve/air bags not going up as expected.  Why, I have no idea.
I would determine if the coach can be lowered down, then brought back to normal level, this would let you know that air bag is getting air.
Sounds like it is not getting the needed air to raise up full extent, mechanical linkage or defective HWH valving.
Good luck

Here is the link to all you will ever need to know about your leveling system.  It's Barry Beam's great site.

Are you on level ground?

Fiddler,
The ride height control valves only control the height of the coach when in the travel mode.
When you press the raise button you send power to all raise solenoids allowing system air pressure to go to all airbags.
How much air pressure do you have while you are raising the coach?
The rear airbags get full system pressure and the front airbags get a reduced air pressure but all should go to their max height.
You have to separate systems,(front and rear manifolds)it's hard to believe both manifolds have developed the same problem.
Are both ends on the low side really low or is one end not raising and effecting the other end?
Do you have a leak that is preventing one corner from going all the way up?
