storing in a heated garage for the winter, tips?

Hi,



my 19FC will be stored in a temp controlled (55F) garage from the end of October to late April / early May. It's a rented spot.



I have a few questions:



- Do I need to remove/unplug the batteries. If so, do I need to charge them once a month? Any charger recommendation?

- Should I remove the propane tanks?

- Can/should I keep the roof vent open (there is a maxair over it) for ventilation

- Do I need to fill the tanks with antifreeze?

- Do I need to lift the tires off of the ground? What if I can't?

- Any tips?



thanks!
