You know, I've posted my toolbox a couple of times but I don't think I've ever put up pics of the cart I work out of every day.
Matco MSC4 (I think), I can do 90% of my daily work out of this how it's set up, without having to reach for something in my main box. Services, Brakes, Inspections, most electrical, etc.
Sockets are all metric because most vehicles including class 8 trucks and heavy equipment are metric now. Socket rack holds 1/2" deep, 1/2" shallow wobble, 3/8" deep, 3/8" shallow, 3/8" shallow wobble, and 1/4" deep. Prybars and extensions on the left rack of holes along with wire insertion tools, radiator picks, and a panel clip tool. On the right side rack of holes, I've got a phillips and flat screw driver, nutdrivers in 1/4", 5/16", and 3/8" along with the 1/4" drive extension/handle for sockets, a pattery terminal ratchet, bent prybar for brakes (orange handle), belt routing tool (red handle), and prydriver (straight shank prybar with green striking handle). Ratchets in assorted sizes and cordless tools live in the free space in the top along with gloves, welding beanie (to keep hair clean), job orders, and earmuffs with radio for those noisy days.
Misc service tools. Filter wrenches/sockets, refractometer, hose clamp tool, fuel line disconnects, feeler gauges, brake gauges, door buzzer sanity tool, blowgun, IR thermometer, etc.
Snap-On Vantage graphing meter and low amp probe, backprobes to get into connectors, test leads, fuse loop (for use with the low amp probe), small set of long reach sidecutters, flush cut sidecutters, strippers, crimpers, zip ties and zip tie puller, 3M super 88 electrical tape, mini torch, single edge razor blades (for cutting into harnesses).
Wrenches (again metric only), pliers, hose pinch-off tools, paramedic shears that cut almost anything, custom screwdriver (because we do a lot of emergency equipment with odd access points).
Hammers, serpentine belt tool (useful for more than belts), hex key indexes, handy-cutter, air chucks (regular and large bore), impact tools, air ratchets, funnels, oil/coolant dye (in box).
I've also got a tackle box with common wire connectors (**** connectors, ring terminals, spades, common weatherpack terminals, etc) in the bottom of the cart along with my powerprobe 3, a ratchet strap for suspension components that won't move out of the way when I need them to, a brake caliper compressor, and most of the aerosols and lubes I use daily (battery cleaner, battery sealer, tri-flow, trans-gel, vaseline or Cat O-ring lube, glass cleaner, etc.) And most important of all up here in Alaska, a snow brush for cleaning off vehicles before bringing them in the shop...
