Mounting Fiamma Bike Rack on Adria Caravan, Refilling the Gas & preparing for new country

We bought a bike carrier for our Adria Aviva 360 DD caravan. It is pretty convenient, but the Fiamma managed to make me angry while mounting it. Refilling Gas bottles is not easy in Hungary (we are talking for the German ones used for caravans). We also bought few more things for our caravan to be more prepared for our ongoing adventure.
