I'm leaving them with my father along with my truck. The muzzleloaders will get a nice heavy coat of oil and then be placed in dry-storage. He'll put my truck to good use while I'm gone. We aren't allowed to ship our vehicles over there on the governments dime. If I wanted to come out of pocket for it, I could. But I'm not. My wife and I will both get some cheap Japanese cars when we get there. You can get a really nice car for about $2K.
I might try to get on some military flights to other countries and do some hunting. Maybe New Zealand or Australia. If I can, I'll just have my dad ship the rifle to me. If not, I'm sure the outfitter will have loaners.
