OK. This coach has a lot of old paperwork which I am still sorting through. Sadly, previous owner was a victim of Covid. I found information and it seems I have RVA Jacks. After reading all of the info I understand the system better. The switch to dump the rear air bags is not working but I have a picture of where the the valves are and what they look like and If I understand correctly I can dump the manually. My air bag system is apparently separate from the air brake system, which is good. My rear bags will lose the air after about 18 hours so in any case I can dump the fronts after 1 day and relevel which results in lowering the coach so the steps are closer to the ground.
Next time I will try the automatic leveling and see if it works.
