Picture 2 is with the bed in a swb with rear kombi seats up and in correct travel position ... the bed then becomes a big parcel shelf.
Picture 3 is kombi seats fold down the bed extension fitted on runners pulls out over folded seats to give you the extension making it a full length/width bed.
If you need to remove bed from van completely there are four legs that utilitize your existing tie down points in floor..... so undo four Allen bolts for your tie down points and lift out. The bed can then be made completely flat by removing the 4 legs from frame and enables you to store the bed as a flat board and 4 separate legs.. tbh it’s handy having the parcel shelf and you can still fit bikes under bed etc
I’ll get a pic later[
Sorry for being dumb but you don't have to fasten down to the floor to secure this bed do you .
I'm taking my van in to be carpeted and insulated in the next couple of weeks and was wondering about the tie down points ?
