Ok, an update. I was able to get the motorhome started and take it to camping world. They pulled the batteries out and showed me the bulge in one and the test meter showed bad cell. Two new starting batteries and I am on the road again.
Also they showed me where the battery disconnect switch for my coach is located. Up in the bin with the inverter controls! My goodness. So back to storage until my trip the middle of next week.
Thank you for helping me everyone. One step at a time. Everything is fine now.
