About us

Charlie Low and Dale Comley climbingvan Ringo yellow sprinter

Back in 2019 we bought our van Ringo and spent 12 months transforming him into our mobile climbing home. With our self-build van conversion finished, we created Climbingvan, an online van conversion guide, wrote a book, and started our electrical system design service. We currently live in Ringo full-time, travelling and working remotely from the road.
