I've been slowly doing a Ford Transit Custom van conversion to cater for different hobbies and road trips! The best solution for this was to have a fold down bed. It saves a lot of space and means that I don't always have a bed to dodge when loading the van with bikes, surfboards, people, beer, and more bikes. Hopefully this will give others that want to do something similar a few ideas!
Massive thanks to all that helped with this mini van conversion. Dad, Andy (Edge Carpentry), Adam & Ben, Kiki & Henry (small amount of carpeting but every little helps), and Bermick (leisure battery)
