No pictures (not much to see) but I have a cap with wired in light, High Lift mounted on the Passenger side bed rail, a milk crate with recovery items and a set of sockets. Small ammo boxes fit into milk crates really well, so I have one with Chain and one with ratchet straps. The pull straps live under/behind my seat. They stay dry up there and don't fit into an ammo can. I keep my bed empty pretty much all the time and set up a small mattress when I need to sleep back there. When I get an Extra cab truck, a fridge will be mounted behind the drivers side seat. I don't want to loose bed space with a mount right now, so it only goes back there on trips. Everything else gets packed in big plastic bins on trips. Modular and watertight. Oh and I don't have a fullsize right now but I feel like truck bed feedback is universal?
When I had a fullsize, I had a cap, below the rail toolbox with all of my recovery equipment (high lift, straps, chain, jumper cables, blanket, hand toolbox, socket set, ect,). The bed was also empty except on trips, again modular packing with a removable fridge and mattress. This was a crewcab truck, so people space was retained in the back seat. Amazingly, I did not remove any of the toolbox items when I downsized, just spread them out around the mini truck.
Anyway, that's what I'm adding to this thread.
