This morning John and Karen took me to Austin to attend to some errands. Karen dropped John and me off at my rig and went to Costco to meet their daughter. While she was gone, John removed my old house battery and then took me to Sears to buy a new one. I got a 12-volt Diehard deep-cycle platinum marine battery, group size 31M. After John installed it, I was able to start my generator with no problem. After Karen returned, we went to Shady Grove restaurant for lunch. We left the generator running with the air conditioner on while we were gone. All was well when we returned. I’m relieved to have that done.
