Air system
I have a 2005 Holiday Rambler and would like to know how long the air system should maintain air pressure when parked.

My Freightliner chassis was only holding air for 8 hours, so I had it checked out at a diesel repair shop. They said that 8 hours was within DOT specs, so it was okay. I still didn't like it, so they checked it out and found a leak at the air dryer and replaced gaskets/o-rings at the fittings. It now holds air for 24 hours, so I guess that I am well within DOT specs. The only thing that bothers me is that my previous coach held air pressure for a month!
