What's difficult for some is simple for others. If your condensor is in the front with it's own 12V fan, that could be what you are hearing and it's cycling because of not enough freon...R-12, R-13B1, R-22, R-502, and R-503 are all freons.

The device that runs every 15 seconds or so might be a small vacuum motor (about the size of a small fish tank pump) that provides a vacuum for the comfort controls. That would run if you turned on the comfort system on the dash. If it's turning off/on too often, than you have a vacuum leak and it's having trouble keeping one of the air control doors open or closed. Check those small black hoses under the dash and out under the hood for a leak. Most auto parts places carry that hose.
As far as the AC system, very few try to work on it themselves as it's big, complex, and difficult to work on without proper tools and equipment. Especially if you have a diesel. Be sure to check RVServiceReviews dot com for your area before letting someone work on it though. You might consider finding a mobile RV service in your area and see if they have HVAC training.
Good travels!
Thanks for the reply. I tried the AC with the engine off and the box under the dash did not cycle on and off. Could it still be a vacuum leak?
