Yeah not a big deal. Had my first AF outside in AK for the winter.
Normal winterization. Drained tanks, pink juice in the drains. Blew out the water lines.
Left it plugged in with the batteries in it on the charger.
I got a soft cover with it when I bought it. The cover got shredded by the ice build up on the sides of the cover when the snow melted.
Kept the bulk of the snow swept off the roof periodically.
I would either just cover it with a plastic tarp next time or tarp on top of the cover. Would have made snow removal easier and saved the cover.
IMO the soft synthetic covers are more for keeping sun, sap, leaves etc from building up. Not waterproof.
