I'm about to head off to the Continent on my first extended trip and I am looking for some (very basic) guidance about filling the Lpg tank. When I bought the van last October it had about a half tank so I've never had to fill it. 1. What adapters will I need? 2 Is all adapter quality the same or is there a recommended brand(s)? 3. Is filling more complicated than petrol? (does it shut off when the tank is full or just explode ;-)) 4. Which country is cheapest? I'm not in a hurry so I will probably have the choice of France Spain and Portugal. Any advice, suggestions or links would be appreciated!
