Charlie Low and Dale Comley (aka climbingvan.co.uk) are two climbers with a passion for design and DIY, currently living full-time in their self-built campervan. In 2019, they converted "Ringo", an ex-DHL delivery van into their home on wheels, however when the time came to give up their 9–5 office jobs for life on the road, COVID hit. And so, with their travel plans scuppered, they decided to use their backgrounds in science and engineering to write a book about how to convert a campervan. Since April 2021, the couple have been traveling around Europe, searching out the best climbing spots, and working remotely with the mountains as their backdrop.
