My understanding is that condensation is moisture/water in warm air. If the storage containers are air tight, no moisture will get in. As a bonus, during cold weather, the moisture level is very low as the water has frozen and no longer a vapour. Provided the containers have not been completely filled to the top, then expansion and contraction will not be a problem. Here in England, if you store more than 2 x 5 litres of petrol [a bit over two gallons], you need a petrol storage licence.
