When we left the USA a bunch of years ago and headed to the western carib we went to a propane
store and got an adapter and some hose. When we went to one country - can't remember which one - we got an adapter and all good -
when we came across the pond in '13 we had our adapter and at some places we could get gas and others not. In Tunisia
we gave them our adapters and they took one of their bottles and did a bottle to bottle transfer. In other countries some will only exchange bottles. It is really a hit miss - In Turkey
we got our bottles refilled at some places and not others and sometimes a guy would fill it and the next time would not. We are on our 3rd winter in Turkey
and last year we got a Turkish bottle and made a slight change to our system - Most want to exchange bottles but our bottle is a different diameter and length than the rest so we do not exchange and at times have trouble getting it filled. We did get it filled in Greece
we still have our adapters and 2 full USA tanks
that we do not use and use only the Turkish tank now as long as we can get it filled.
