The van had one of those loo containing buddy seat boxes that was free standing and wasn't fixed in. This was no use to me as it couldn't be used while on the move. I have 3 small children and so needed an extra spot big enough for a group 1 seat.
So, i picked up one of those quick-release, multivan flip-up jump seats from a show and fitted it instead. My van didnt have any of the fixing points for the retaining bar and so rather than drill through the wheel arch, i used a length of metal bar fixed to the seat box inside the cubby hole. You can't really see it when the retaining bar is fitted. Next I drilled a couple of shallow holes into my ply floor and job done.




Now when we go camping, all 3 kids have a proper seat with a 3 point belt and when we arrive, I throw up the kyham and chuck the jump seat and all the kids seats into it. Sorted.
