Great article in the just-arrived Sept. FMCA magazine on compressed air system in a diesel pusher. The model described is a Freightliner chassis, but if you eliminate the air service brakes, the rest is good at least in theory. Discusses compressor, governor, suspension, parking brake, air dryer, and air storage tank, as well as cycling limits.
Actual WRV parts & cycling limits may vary, but will perform the same functions.
