I've knocked up a table using an off-cut of MDF and covered it with the left-over of the Silver Vinyl that I used as a wallcovering in the kitchen area. This has a screw-off leg and folds away behind the crew-seat when not in use. It also sits across the battery-box seat as part of Josh's bed. The third bed (Josh's) is now formed by swivelling the front passenger seat facing rearwards and reclining the back flat with the headrest removed. The table has 2 battens on the underside that sit each side of the battery-box seat to locate it & prevent it from slipping off. I am using a roll-up self-inflating camping mattress that sits over it all when in place. Similar to the main double-bed, takes less than a minute to put up.....
I've also tidied up the fuse panel area, and made a proper click-shut access door for it. I've cut a bit of foam from the old over-cab ambulance doors to make a backrest for the 'battery box seat' and covered it with some of the old grey carpet that covered the now removed cab partition. I've also lined the battery box seat and surrounding MDF with the last remnants of the carpet and started on the last bits of exposed cream-fibreglass from the ambulance interior with my grey van-lining material. The cupboard doors have eventually been trimmed & fitted to the over-cab storage area. Part of the off-cuts have been used to make the backrest to the 'battery box seat'.
