Tried to get advice on this before(elsewhere}.My german import hymer came with the german green bottles and has an auto changeover system.These bottles can only be refilled for me in cork.I see some vans with german systems and they are working fine but heard of potential problems of damage to heaters etc.So please reashure me that it will be ok and tomorrow I am going to replace the pigtails by pushing on orange hose and a clip to the gas pipe ends on the van.Bite the bullet time and I can change bottles in any shop(in the south of course).Good to go?
