I don't have enough posts to link my images but I have a Milwaukee folding cart I use for work. Works great and I plan on getting another. I have my bag set up pretty well and will add a few "Plano" style cases to it for extra screws, clips, glow plugs and any other parts I may need.
My job has me in different shops and buildings everyday and I need to bring a VERY wide variety of tools with me so I make sure to keep my setup as mobile and convenient as possible.
I am really amazed at how much stuff I am gathering and seeing a need to take with me when I run. I have researched almost every tool bag available for my tools at work and have a few in mind that I am going to look at for this hobby now. I will post back pictures (whenever I reach whatever post count I need to.) and layouts of what seems practical for others to check out
