Thanks to all the great people who responded with advice on our lack of air Pressure. even the fellow who lives nearby and told us of a good donut shop and local activities!!!. I talked to Comins and they didn't think a mobile tech could definitely fix the problem they said a mobile took could cost $700 and no guarantee of fixing the problem, as it could also be a governor issue. To answer some of the questions , fan belts are fine no slippage, I did not hear any air hissing, the airbags remain fully inflated. The man from Cummins asked if I noticed any blown hoses. he indicated this is a very unusual problem. I didn't see any sudden drop in the air pressure , but it dissipated over a period of hours not right away. I got no water out of the air compressor chambers underneath the rig but up not changed the desiccant filter in several years.
Thanks to all for your help, great forum.
