Plain and simple there is a leak somewhere.
Get yourself a spray bottle and mix up some liquid dish detergent and water in it. Then just go along and check all the fittings on the system. Just spray a good amount of liquid on it and look for bubbles. It might help to do then when the compressor is running.
When you find the bubbles you found your leak.
Just as a FYI my brother in law has had some Firestone air bags on his truck and they have held air since they were installed a few years ago, but he didn't go with a compressor just one set pressure since he has a slide in camper on the truck full time.
