I am currently on a multi-year climbing trip, and for it, I converted a Ford Transit into a camper van.
I made this video about the build..
It was actually surprisingly popular - and the feedback was amazing - so I decided to go the whole way and document as much as I could about the build.
I hope this blog is useful for your conversion, if you need more information consider buying the ebook I wrote about it - more about that here.
You can find out more about me on my other blog here; http://njmurphy.com/
All the best, and I hope to see you on the road!
