I can't answer for Steve but, I do know he'll ans your email at some point. There's a fone number listed as well..
You've raised a few valid questions. (propane tanks being an excellent one) You might ask the guy your sending this to what they use over there..It could even be that he might wanta put his own on there..?? I, for sure, wouldn't send them with any propane in the tank~!~ KWIMC?
Just a thought..Maybe if you called the A/S factory to see if they've had any experiences with oversea shipping?? If so, might be worth a bottle of wine to "grease" some palms..lol
