Thanks for the reply ATVer. The symptoms did not begin until after the awning motor was replaced by Camping World. It was under warranty. I had no problems when it failed. My son checked the batteries and his tester said they were good. I do not see any place to check water in my batteries, just compartments that say they have acid in them. I don't see any fuse in the step. I drove 800 miles and the batteries did not charge, in fact they drained almost totally dead. I am home and plugged in. Some charging is going on from shore power, but very little. It seems to me that something is draining the batteries faster than they can charge. I am wondering if it is related to the awning motor replacement. I'm calling Camping World tomorrow.
