So I have been chasing an elusive air leak for the longest time. Today I happen to find it by accident under the bay while looking for a missing front salon electric heater. There is a solenoid there for what should have been a step cover. I do not have a step cover on my coach as it seems it may have been removed. Can somebody post a pic of what I am missing? I will repair the leak with a compression fitting. I also found what appears to be some previous source of major heat that melted the insulation in one of the bays.
