One of the challenges storing a closed unit outside with no climate control is humidity. This can cause all sorts of issues that are better off to be avoided in the first place. It is fortunate that the Northern-Lite 10-2 is close enough to allow a 110VAC cord to the unit to allow all the 110 outlets to function throughout the off season.
To combat the humidity, we have a Davis 1458 Air Dryr 1000 (from Walmart) plugged in and running 24/7 along with the usual Damp-Rid hanging bags. These two items, along with an occasional Glade air freshener keep things hospitable while the unit is closed up.
