Is There A Way To Shelter the Rock Climbing Machine?

Well, glad I gave Google a whirl before posting here about this myself. I've got a rock climb rig that won't repair no matter what, and was wondering why, and it looks like it's not meant to be outdoors anymore.

Well, in terms of making a shelter for the thing, what dimensions do I need to work with? I know the thing can tilt some, but is that still within its default "footprint"?

And, when I say "shelter", will a three-wall-and-roof design suffice? Or does it need to be fully enclosed?
