Of course I'm still learning

indoors is better than outdoors and covered outdoors is better than out in the open. if it were me and I had the choice I'd enclose or at least cover the parking spot. if you're gonna enclose and you have the space make it long and wide enough to get the slides open, you on the roof and so you can walk around it. that would be my dream.

I would not opt for a one of those large vinyl or cloth "bags" that enclose the MH. too many people report damage (scratches and the like) or the "bag" getting damaged by wind and snow.
