No miracle air pump, but I often have enough air pressure from before I shut down. My coach has air leveling and if I'm stopping overnight, I don't purge the tanks and dump the air. Furthermore, when I stop at a rest stop or restaurant while traveling, I don't purge my tanks either. So yes, absolutely, I can get going in 10 seconds and have enough air pressure to release the parking brake. While I do listen for the spitter before going forward, I also have a backup low air alarm and it doesn't usually go off at all unless I've purged the tanks to put down the jacks the night before. It's really not that mysterious.
If you have air bag leveling you have a electric air compressor that keeps your air pressure up.
Most coaches have to use the engine powered compressor to build air pressure.
