Were off to Spain very soon, (first trip in Europe in Motorhome), we have 2 6kg bottles on board. We expect to be staying on Aires through France and probably using more gas than we would normally use in the UK as we like to use sites with EHU. Any idea how long a 6kg bottle might last with normal use, hopefully not too much heating in April. Also, can one get propane refills in Spain. Your thoughts and experience would be very welcomed.
