One of the big problems I had was overcrowding, especially as I acquired all the special tools needed to do avionics and firewall forward tasks. My approach became multilevel and I don't have pictures of everything but here's what I did:
I got a heavy dresser (you'll see it in the picture below) which I turned into my bench top. It has my vice and holds a small drill press, grinder, and stretcher/shrinker. It's drawers are large enough to hold larger tools and items.
I have a craftsman rollaround set which has the organizer trays (sorry, I don't have the model). The lower part holds larger tools, the upper box has a drawer for files, one for odd sockets, and one for miscellaneous drill bits (long ones, reamers, wood bits, you name it). The organizer holds step bits, driver bits, countersink and bits, punches, and so on. The tray in the upper box holds all those little tools, templates, widgets, etc. that I made myself specifically for the RV.
I try to buy tool sets that have their own holders, so I have drill bits in their own holder, a craftsman socket set in it's own carrier, a nut driver set in its own case, die sets, and so on. These are all laid out on steel shelving that has been made in two sections so that it's not quite a waist high table but works well for access to tools. For building, I get university surplus folding tables (where I also got the dresser) so the shelving is strictly parts storage and tool layout.
That still leaves a number of tools I like to have to hand, so I built the A-frame in the picture, covered it with peg board on one side and particle board on the other. I used the particle board to pin up plans sheets but I don't need that for the -10, so I'm thinking of replacing it with peg board on the other side and hanging more tools from it. It's on wheels and I find that the frame between the sheets is a handy place to hang the larger clamps from.
While I was at the University Surplus, I also snagged a 4-drawer file and an old metal desk. The former is handy for keeping documents relating to the project and the latter is great for reading plans, filling out logbooks, etc. - all the paper tasks that a project floats on. It's not a bad place to do electrical work, either, though I just got a bargain on a task station (University Surplus again. Surprised?) Oh, and when I built my avionics kit up, I got one of those tackle boxes with pull out covered trays for lures and a main box above the pullouts. The trays hold sorted components and the main box holds the crimpers, cutters, picks, strippers, and such. If I tried to fit all this stuff into a single rolling tool box, forget organization; how would I keep the thing from exploding?
