Put it back to sleep today for the rest of the winter. It was asleep but the weather was dry between snow storms so I got it out for a few days to exercise it a little. I now know the heater works. Back on the battery tender in the garage until April. I'm heading south and the XF is just to small to carry everything we need for 4 months. I would look for a XF in Florida but I don't have a garage and hate to leave one out in the sun for the summer. This way I have something to look forward to in April.
