Mustang, I see this is an old post, but I just saw it. I have the same setup as you: 2012 F350 6.7 with Airlift 5000 and on board compressor. I had the bags for a few years before I added the compressor (last year). Yes, it cycles infrequently; sometimes every 5 minutes or so, sometimes not for half an hour, sometimes 2-3 times in 5 minutes. I went over every connection with soap spray and found no leaks. I contacted Air Lift and they sent me a new manifold. I installed it and it made no difference. So, I soap sprayed again; no leaks. I noticed the cycling was more prominent when the 5th wheel was hooked up and have now deduced that the cycling is normal. When the remote is set at a specific psi, temperature fluctuations will play with pressure and the automatic system will try to maintain the set pressure. Sometimes, mine will kick on and add air, sometimes when I pull into a parking lot, I can hear it releasing air. Weight of the 5 also plays with pressure. Road movements, will compress and expand the bag, making the pressure monitor activate. Finally, to wrap this up, for my purposes, the cycling compressor is normal operation and has worked, for me, with no problems, for about a year. If you have found different solutions, I'd like to read about them.
