XRAY - Model racing cars

I now have two electric and one nitro SCT along with two radios, chargers, tools, and spare parts that I bring when I go out. Right now I just toss the R/Cs in my truck's bed-mounted tool box and bring a 24" toolbox with spare parts, a 12" tool box with...tools, and an aluminum case with the radios and chargers.

I know there's gotta be a better way to carry them so I'm looking for ideas. I was thinking about one of those R/C-specific pit bags, but they seem too overpriced. Maybe a bigger plastic toolbox from Home Depot? Mostly looking for a way to keep all the spares and tools organized. I have a few of those clear-plastic parts organizers for screws and connectors and such, but the tools just get tossed into the bottom of the 12" box, so it requires a lot of digging to find what I need.

Pit bags are actually really nice. I have the OFNA one with rollers that will hold everything I need for a day trip. Cars go between the handles on top. I stack mine up and stagger them. E Maxx up top, Revo & T Maxx on the bottom. I flip the handles over the tires (only one axle on each car) and pull out the collapsible handle and drag it behind me (works best on smooth clean surfaces ).
