Thanks Steve. I looked at quite few of the documents there but could not find too much information on the air lines schematics for that age. I guess I will have to get under there and see what I can see, I can always cut in a couple of air solenoids and some switching to dump the air bags manually. The newer units seem to have it as part of the hydraulic leveling system.
Once I look under there, I can give the beaver people a call, and have some idea of what I've looked at so I can ask intelligent questions.
Thanks for the response. We are looking to drive down to Quartzsite in January, so that will be a shakedown run for us in this rig.
