Here's the bag.
For brush and rakings, I'll stick to a Husky garbage can. You can tie up a good rakings-and-tarp burrito, and put it on the trolley.
I often have a half-sheet 4x4 piece of plywood around. You can make a platform on the trolley without stakes, simply by tossing the plywood on top, maybe a ratchet strap with a round-turn on the trolley frame. If you were feeling crafty, just put 4 holes in the plywood to accomodate the plywood slipping down over the 4 stakes, locking the plywood into place. I never thought of that before.
To me, its stupid to hand carry hundreds of pounds of gear into a backyard with many trips, plus roll the trolley. I think you can stack 'typical' Rubbermaid storage bins in the bottom, but I don't quite recall. The mini has reduced AT use by a long-shot.
Even short of having an Arbor Trolley, hand-trucking gear in, and wood/ fir-limb bundles out saves so much effort. The wheel and axle have greatly advanced civilization.
Load hand tools, saws, ropes, lowering devices, crates, etc.
