Here's an update on mine, after living in the shop for a while...
Ratchets, breaker bars, chrome sockets, extensions, adapters, screwdrivers
Hammers, picks, punches, chisels, test light, jumper wire, tape measure, misc stuff.
Pliers, cutters, strippers and crimpers, adjustable wrenches
Combos, Stubby wrenches, SAE flare nut wrenches
Everything impact, air ratchets, CAT strap wrench socket
Side box with prybars, picks, larger screwdrivers, extensions, and slide hammer
The bottom is also loaded down with stuff, including my torque wrench, bottles and cans, funnels, bag of rags, and some misc working AC parts people wanted replaced. It's weighed down pretty good, but still holds solid. Some of the drops and potholes at the shop make me nervous though...
