The air bags on my big truck normally leak out over the course of several hours. If it is windy and rocks your RV it can lower air pressure even quicker as the suspension wiggles. If your RV has air brakes you can try doing the air brake test the big rigs use to check for an air leak. Since the same air supplies the suspension and the brakes it will cover all the air system.
You should loose less than 2# in 1 minute when static per DOT.
120# nominal air pressure divided by 2 #/min = 60 minutes. Since you last a couple of days, you appear to be fine.
