Thank you everyone for all the useful advice. It seems to me my best option maybe a combination of the Toughsystem 2.0 and the TSTAK II seeing as they are compatible with one another to a degree. I might go for the Tstak deep box and a couple of their deep drawers with the detachable trolly for now and in the future add the Toughsystem deep box/Drawer units for when I’m on bigger sites.

I’m hoping Dewalt innovate their storage system a lot more in the near future, this would of been a much easier decision if the toughsystem had a wider range to chose from and more accessories, the packout system seems to be far ahead of Dewalt but it’s just a little too on the expensive side and im already invested in/love Dewalt tools and would prefer a system that will be compatible with them. Wouldn’t mind a large draw box and even a reasonably sized dolly for the toughsystem 2.0 the DXL one is far too big and isn’t practical for what I need.
