Brian - I've thought of taking the fuel out of the tank as well but haven't really anywhere to store it :(  Also thought about buying a run-around and leaving it in Tortosa but having weighed up the options, I don't spend enough time there to justify it.  4/5 weeks a year isn't enough and the way the Irish and spanish economies are heading - I don't see any prospect of spending any longer there in the foreseeable future. :'(
