Will audio gear be ok in unheated house

I have a cottage.   I drain the pipes and the house is left unheated over the winter.  I have been taking my audio gear home (except for the speakers)  when I leave in the fall  for theft worries, but  mostly because I am not sure  the equipment will be OK in an unheated house in an often damp environment until the late spring when I return.

It is a pain taking it back and forth and I would prefer to leave it there.  Maybe in garbage bags with some bags of dessicant in the garbage bags.

Anybody have any experience with this.  I have been unable to find a good answer searching the web.

Thanks
