How are you going to refill the gas bottle. Before i had the underslung tank recconected i went to a garage/ camping shop and the guy looked at my german bottle and said i would have to change(the bottle) for an English one. Two other sources have said the same. One of them works for Gasure the other is another member who has a 'Westy Joker'. The latter took his german gas bottle to the tip, which is where mine will be going shortly.
Have you not got an under slung tank on your Westy?
