Questions for Royale owners
What should my auxiliary air pressure be set at?

Whatever the minimum pressure required to operate whatever is required should be a cut in pressure. In other words if your aux air is required to open a holding tank valve or move a pocket door, that becomes the lowest pressure or cut in point and the pressure differential usually ranges from 20 PSI to 40 PSI.
If you want to air up your belt tensioners for example and they have a pressure requirement of 65 PSI, use that as you cut in pressure.

Your aux air system operates the following items on your coach.
Slide Seals, step well cover, dump valves. For these items you only need about 30 lbs. That will also keep tension on the belts.
It also operates the leveling system. If you want to use auto leveling and have it maintain level, you need 100 psi.

Thanks Jon, Mikee, the information is appreciated.

If the slide seals only require 30 psi and your other devices need a higher psi,
what keeps the slide seals from rupturing? My compressor shuts off at about 120 psi, after about 3-4 days when pressure drops to about 85 psi the compressor cycles again.

Pressure regulator.

Roy, The simple answer is to keep your aux pressure as low as yu can get it and still have the use of all the pneumatic devices yu use when parked.
Keith, as Tom mentions you have a pressure regulator that should be set around 10 PSI for your slide seals, usually in the 3rd bay back.
