Dang, Tom, I was afraid you'd show up in this thread. I just decided not to post pics of my F-SuperDuty w/ the 10' bed.
My first service truck believe it or not, was a Toyota 1-ton 4x4 w/ a 7' service bed from 1989-2000, then a SRW C-30 w/ an 8' bed (like yours), then this fall I got a 16,000 gvwr ford w/ a 10' bed and top boxes.
I have organized all my trucks the same basic way.
On my first 2, the hand tools were in a drop-front tool box right behind a the drivers door, on top of the bed. On this truck they are in the top box on the left side.
Mounted to the top of inside front compartment, drivers side is a 1500w inverter w/extension cord and trouble light reels. The inverter runs off of a series 31 battery in the front corner of the bed that also starts my compressor and runs the floodlights around the truck. The battery is charged by the truck alternator through an isolator, or by a 125 amp Delco run by the compressor.
The top shelf in this compartment is a junk shelf and where I throw parts when I come out of the store. The second shelf has my parts and service manuals, though a lot of them are now on the laptop behind the seat. Next shelf has welding rods, welding helmet,hardhat,gloves, rain suit, and various other supplies and etc. The bottom shelf is where I keep oils, fluids, and chemicals.
The horizontal compartment top shelf, has my air and electric tools, my diagnostic tools, my 3/4 and 1" drive extensions, adapters, universals, and 3/4 sockets from 3/4 to 1-3/8. The bottom shelf has wrenches from 1-3/8 to 3", pipe wrenches, pry bars, torque multiplier, driving rods, and other large tools.
The rear top shelf has chainsaw parts and tools, GoJo and a few other things. the second shelf has rigging such as hooks, straps, shackles, etc. The next shelf has funnels and hammers, and the bottom has jacks and a fire extinguisher.
Right inside the tailgate is a 7 gallon aqua-tainer in a milk crate for washing hands, etc. Also in the bed are a lot of wooden blocks, shovels, ax, gas for compressor, etc.
The front compartment on the right has 3/4 and 1" dr sockets, wheel bearing sockets, power and manual grease guns, grease, jumper cables, extra air hose, extra extension cords, rubber boots, and other bulky stuff.
The horizontal compartment has parts and hardware and emergency canned food.
The rear compartment has the cutting torch.
and last but not least the cab is full of small parts, junk, trash and other stuff that shouldn't be on a truck. Oh, and behind the seat is my laptop and cold weather gear.
