One of the coolest layout features that I've seen (and that I wish I had) is an arrangement that has an area of dedicated cabinets/shelves ***built specifically to hold/retain standardized storage bins.***
It's something I've seen on several rigs, the one that comes to mind is one that forum member BettyFord sold a year or so ago. It was an SMB RB30 buildout that looked to have a wall towards the rear of well-secured (and well-presented) rugged clear plastic storage bins. (Perhaps this is what some of you guys refer to as "Action Packers"...?)
If I've learned anything after almost five years of living with/traveling with/working on these vans, it's that the easier you can make your task of loading in/loading out (and staying organized along the way), the better.
(Also --- these vans are indeed just like your average car or truck, in that they need to go to a repair shop frequently enough....so if you can **simplify/streamline your task of getting all your personal items out of the van** before you drop it off to a shop, that's an added bonus too....)
EDIT: just found and attached the only picture I could find of the shelves in the van BettyFord sold (this picture was on the eBay listing for it....) There's a sweet organized area of bins just past the gaucho couch in the rear of the van.)
