The night before we left London for a week's camping on Exmoor, Graham and I thought we'd be terribly efficient and load up the car and roof box that evening to make a quick almost-dawn getaway down the motorway the next day. We lugged the enormous and unwieldy roof box and its bars through the house, out onto the street, and discovered that they don't fit on our new car. We looked at each other in disbelief. Our tent alone normally takes up almost the whole boot.
We took a deep breath and just took one bottle of cider (for me) one bottle of porter (for Graham) and the two bottles of mead (not negotiable), reasoning that we were heading to the West Country so we could buy more when we got there.
We left the gas stove behind and took the two trangias instead. In the end we only used one of them.
All they needed was a supply of toasted marshmallows, and a change of dry clothes occasionally.
