Low Tech--no Tech--holiday Innnnnn...
This is a decidedly less technical temporary solution. It happened to be free for me, because I have access to lots of weather-resistant nylon "coffin" bags in my line of work (transportation). Before, my cargo area was a hodge-podge of duffle bags and loose equipment. This bag helps keep my stuff consolidated and not flying around the cab, not to mention my truck spends some time in some "shady" parts of town, and the black bag isn't highly visible from the outside.
I have thought of doing a drawer system, but I also sometimes need my third row seats for taking my big family around town. The bag can also go up on the roof and be strapped down to the roof rack via the nylon grab handles.
It sits comfortably in the cargo area, but slides out easily with a pull on the two front grab handles. The grab handles on the sides also serve as tie-down points for gear I can put on top of the bag. The bag has an internal frame of plastic sheets that keep its sides upright. Inside the bag I keep various other bags that organize my gear.
Yellow bags: tire repair equipment, jumper cables, fluids, maps. Underneath yellow bags is a complete 150-piece tool kit
Little blue bag to left of yellow bags: Baby kit, incl. formula packets, diapers, A+D, baby wipes (don't laugh)
Underneath little blue bag: Sleeping bag
Underneath sleeping bag: tripod seat. With my back, I gotta have a place to sit.
Action Packer to left: Camp Kitchen/Food/Water
Black duffle in front of Action Packer: Survival gear, "Leaving Car Behind And Hoofing It" emergency gear, water purifier, hygiene, etc.
Blue zip-up bag with plastic window: straps. Lots and lots of straps.
Blue thing with flip-flops on top: Thermarest for a good night's sleep.
Basically this is all the gear, food and water I need to go remote for a few days, even with my wife, baby boy and another adult, and be fairly comfy. I had an incident last year when a day's work foray in Santa Barbara County during a landslide turned into a four-day lesson in self-sufficiency. I'm really glad I was prepared. When other trans people and stuck workers were milling around in the cold, waiting for relief help, I was heating up chili and beans, sipping bourbon and watching DVD's from the comfort of my mobile hotel room.
I always have that hideous camouflage Becker Patrol Pack at my side. It holds a ton of s*** comfortably and if I ever needed to leave the truck and hoof it a long way (ie trail break-down), I'd need a way to haul all the gear I'd need. Best bag I've ever owned.
