Hoist for campervans and wagons!
I recently watched an episode of George Clarke's Amazing Spaces, where a young man with spinal muscular atrophy had created a self contained travelling wagon. (I highly recommend watching the episode, if you can, it is available on iplayer for a short time!)
A friend of his had come up with a unique hoist design that I'm really interested in and I found out he has a website! check it out .. travellinghoist.co.uk
