This is what I brought with me to the DSF course
It’s pretty durable, and there are 4 or 5 different components that you can mix and match to suit the needs of any given day. Its lighter than the metal versions, so if you have to hoist it, most of the weight you’re lifting is your gear. It rolls and controls easily, has extra large wheels so it’s good on rough ground. Large heavily-made latches and weather-tight, from my experience.
And it breaks down into smaller kits for when I have to lift it into the back of my truck.
Its plastic, so it may not be as durable as the metal versions but for portable organized storage it’s very sturdy and substantial. I’m very happy with it… it’s what I use.
Here’s the full set of components:
At home, we have a storage area with metal shelves for ammo, much of which is stored in ammo cans, and the safe. We’re going to add some metal garage-type cabinets.
