What did you do to your Class C MH today???

Although it was a mild winter, I've neglected the RV until today. Took off the cover and tried to start it but the battery was dead. Tried to jump start but nothing. Took the Duralast battery into Auto Zone and they charged it for me. Seems to be OK, just so dead it couldn't start even with a jump. They had me return in an hour to pick up the charged battery and I brought it home and reinstalled it. Starts the engine now.
I guess it is time to get back to camping...
