Quickest ever Camper Van interior install

This is a modular kit from a British company, made for VW Eurovans. But I thought it was an interesting idea, to make an entire interior that do not actually bolt to the van. They're made to be easily removed if you need the space!

Wow, once the cushions go on there, it looks really nice! And the center section kinda locks everthing in place. It gets you thinking...I wonder if it bounces around when riding down the road. If your on a rough road, I wonder if this stuff rattles around.  Seems like if it had some way to quickly attach and release to avoid the movement and rattles it could make this even better.

GOTTA admit its cool and eliminates a ton of work also it would be nice if they came in different styles and for Earley American vans also.... I will take a wrap around rear booth seat.!!!!!!!!!!!!   I am sure there is a way to bolt it to the floor if you choose too. ...Any VV vanners good with fibreglass and making moulds??????

Looks like the pieces in the floor keep things from sliding. Some 2" velcro to join the pieces together could eliminate any rattles. I like it!
