Just want to provide an update on my air leak problem. After leaving it for five days at the Freightliner shop in Lodi I still had an air leak. Stopped at Florence RV in Florence, OR and he solved the problem within minutes. Had a leak in the air brake control and it showed up with soapy water when sprayed on the top of the panel. Also the air horn relay had overheated and melted the plastic air hose. The relay is in the compartment where the fuses are on the front left. Thanks again for all the suggestions. As you can probably tell, not mechanically inclined but learning.
