Covering the bike in the garage (condensation)

Hi guys so I have the Oxford stormex bike cover for my monster 821 but noticed when it is under the cover when the weather suddenly changes it builds allot of moisture on the bike. Even under the cover. The garage has metal roofing so build a little bit of condensation and drips now and again into the bike. Would a dust cover/ cover made for a garage work better than a insulated outdoor cover. Would that help with build up moisture. Any suggestions would be welcome. As I don't want the bike left uncovered if it's getting driped on. I don't own the garage so I can't make structural changes. Thanks.
