Got it fixed. It was a bad water heater element and bad 12 volt relay. Want to say more but this site says improper formatting, whatever that means.
Update: figured it out, it was me putting brackets for use as parentheses. here's what I meant to post.
All-right everyone, the rv repair shop said 100% it was a bad Atwood Water Heayer Electric Element and a bad 12 volt relay. He said something about the switch on the control panel, I think he had to do something to it. Maybe turn it upside-down? He said that because there was no water in the tank, then with the switch apparently being in the opposite position in the "off" position with the faint red glowing light that that may have been what was causing the element inside the water heater tank to burn out. Then again, because this is motorhome is new-to-me and has had what seems like more than a few owners, then it's likely that someone else in the ownership line before me might have burned up the water heater element.
