I guess this would be under the dumb-ass topic...I overflowed my fresh water tank pretty bad that my power went out. I turned off the 50 amp breaker outside and am letting things dry...did I do major damage or will things get back to normal when it dries out. I have a 2005 Fleetwood pace arrow.
Shouldn't be any major damage. Threw the breaker is all BUT I would want to know how water got to any electrical wires. It's not typical that water would get to anything but I don't know where your tank is located or what's around it. Mine is in the front bay and no electrical (other than 12 volt) that can get to it.
Tank overflows usually end under the flow. If you have water inside, something gave. Proper inspection is in order, but disconnect the power before going there.
