oldmattb,
Most likely the front one is for "air-in". That is, if you should ever need a tow, and your air supply is low enough that the brakes are on and, you cannot build air from your own engines compressor, a tow truck can back up to the front of your coach and hook up their air system to yours and build up yours so that there's enough air in yours to release the parking brakes so he can tow you away. That's also presupposing that there's no "shut off valve" (like we have on ours) that was shut off and that's why you had no rush of air from it when you removed the quick release fitting. That's my guess.
