DIY rock and roll bed

[Azzman1000]

First question is if anyone is going to travel in the seat?
If no one is - then it doesn't matter. Stick a couple of milk crates tied together in there and whack some foam over. 

If you want people to sit there while you are driving - that's a whole new ball game.

I doubt it would pass as it is not an existing seat.
Only Westfalias were sold with the r'n'n
All others were VW modified and would have come with an engineers certificate when new 
These days you cant use a plywood - needs to be a steel frame.

Thanks Barry,

I do plan on having people sit on it. I’ve removed the rear seat when heading away on my own in the past so I could set up a bed in the back but I’d like a more convenient solution.

Sounds like it’s going to be a bit difficult and expensive though.

Cheers.
