If your concern about the heat and mositure for the machines, put some charcoal in a old nylon and store it with the machines. That will help control the mositure. We were told this years ago, when we traveled to and from Guam with the Air Force. It worked great and we did not have any damage for the shippment took three months to get there. Also take plenty of pictures and add the machine to your homeowner. That should be done for everyday too. Good Luck.
