Pneumatic Levelers?

[Slum Jack]

I've got a '78 Dodge "Establishment". 24' and duallies in rear. There are air nipples in the rear for pneumatic level adjustment.

I was also fortunate enough to get a buncha' original manuals with this rig, including for a number of the cabin/RV systems. And I chased down a manual for that year's Dodge Van. But haven't found any reference at all for these levelers and am completely inexperienced with such things.

Suggestions for reference/guidance? Resources?

Thank you!

I believe I probably have something more like you explain at first. I've got a bi-directional level installed  in the walls inside the cabin. But I'm wondering how to determine this, for sure. Naturally, this could have implications on just what inspections, maintenance, etc. I ought to be doing.

Do you know of any way to tell more certainly?

Hi,

   If you have air shocks there will be a air line (about the size of a pencil) going to the top part of the shock absorber/ air bags.  That air line will run to your air nipples in the rear.  If you post pics someone here will know for sure.  Hope this helps, Tony, Joy and Cool Paw Luke

Thank you very much. I'll check. If I can't puzzle it out, I'll take some shots and post.
