HA!!
Anyway to explain briefly my 'system'.
The big box at the back has loose power tools. (it's screwed to the ply floor).
The F&E tank next to it is also screwed to the floor. That's got tubes of silicon and gas, etc in it.
Against that I normally have my tote bag full of tools I take in on the job. (It was on the job when I took this photo!).
Then is my 'engineers' box. Which has all sorts of crap that I don't use often, like smoke pellets, pressure gauges, glass fuses, water finding paste, the list goes on.
Then I have my 'hop up'.
Then I have my tool box full of hand tools I don't often use.
Then I have my pipe freezer.
On the left hand side racking is useful things like hose adapters, jubilee clips, tape, etc. On the right hand side I have my large plastic tubs. Filled with waste fittings, comp fittings, pumps, valves ect.
Then I have my Makita cordless drills in one box.
Then I have drill bits, jigsaw, crimpers, and all manner of tools. Then on the back I have my benders, formers, hose pipe, cable, kitchen roll, U gauge and the like.
I love working out this van. compared to the old one, my stress level has less than halved!
