Off to France and Holland for 9 days. The gas is not usually a problem but we are only staying 3 nights at a campsite near Amsterdam with hook up. The rest will be gas only..the problem is we have two 6kg Calor Lites and one is about half full, the other has a bit out of it ( daughter went camping) not sure if they will last. I have a couple of friends who have vans and am hoping they may not be using theirs and we can maybe borrow one. Any other ideas? I will be looking for Aires with hook up as well. Thanks
