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?
on my old rig the air nipples let to the shocks which were and still are a standard Firestone air shock system. I just put a carpenters leve inside over the axles and leveled up the rig. When i use to carry the motorcycle on back or tow the boat I just added a little more air until everything was level. If I wasn't towing I'd just let air out until the rig was level for highway travel.Pretty simple IF this is what you have. Two points; they are not for leveling the rig in every uneven campsite... a few boards work well for that, and the airbags inside the shocks crack and leak air after about 4 to 5 years, but can be easily replaced. If you have hydraulic levelers that's a whole different deal... for leveling the camper at the site.
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?
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.
