There can be dozens of potential locations for air leaks, the air dryer is one of them but other than in freezing weather, not one of the main suspects. As a reference, Newell does not consider air leaks to be significant unless the 120 volt air compressor is coming on more often the every 40 minutes when the coach is parked. That said, some of our more industrious owners get hours between air compressor cycles by frequently going through their system and resolving small leaks.
Basically, every connection in the air system is a potential source of an air leak. The ride height valves, the pneumatic cylinders, the air suspension control solenoids and the fittings to each of these are some of the primary sources. The air operated pocket doors, air operated toilets and the fittings to the air drivers seat are the also sources that should be investigated along with any other items in your particular coach that use air (dump valves, dryers on the various air compressors, pneumatic slides in the bays or for the generator, etc). Large leaks can be fairly easy to track down, smaller leaks will benefit from a sonic leak detector.
