Quoted from FelixTCat:Can you find a temp controlled storage unit nearby and just move them into that ? I personally would be concerned with the movement of the POD and anything falling over / taking a bit of a hard set down. With a local temp controlled storage unit you know you moved them once and they are stable.
Yeah a lot of the Storage Units built in the last 5 or so years are temp control.
Also a thought....if any other pinball folks are in your area see if they have the space. I once took on 10 machines for another Pinsider while he moved.
