I run the Construction Crew for a local government agency and wrench on everything from the chainsaws to graders and haul trucks. I ended up using a Montezuma portable top box ,item #: MTZ-SE250, from Strictly Tool Boxes, works great, I can slide it from the bottom box to the back of the truck without lifting it. It has the cantilever top that took a little getting used to. But i was going through the slides and beating out the bottoms of the conventional style tool boxes, and was replacing them about every other year. I don't have any pictures, but there is several examples on their website. Nice thing is you can work out of it in the shop and when your out on a road call, you have all your stuff right where you can find it. I was the first in the shop to use that box/system, now the rest of the Mechanics are converting over to it after seeing how well it works. Cheers!
