When Camping World opened this morning a tech came and looked at my camper and determined he thinks that for some reason my water lines became pressurized and that the water pump is ok. This is good news. We also could hear the pump but cannot find it. It is behind a wall which would not be an easy fix if it goes bad, which hopefully won’t happen. I hope the pressure issue resolves itself.
As for a roof AC unit, will hold off for now. If it gets too hot, I will turn the van engine on and use the dashboard AC.
Now, time to start my drive through Alabama towards Texas.
