Bermy

I live on a small island and my van is parked on the mainland so most of my stuff stays right in it. Wet kit gets taken home to dry, just sling it on the balcony in the shade.

You all would laugh at the size of it, but we have strict vehicle size restrictions here...

I have a shelf right across the back load area. 5 chainsaws go underneath, handsaws, levers, sledgehammer go on the sides over the wheelwell.
On top of the shelf I have plastic containers on the sides for slings, crabs, wedges chains...all that little stuff. I attach a portable vice to the shelf for on the spot maintenance.
Gas and oil are in a separate container, like a milk crate with no holes in case there is a spill.
My climbing gear is in one rope bag, and small and medium rigging ropes also in separate rope bags. Spikes, port a wrap in a milk crate. Everything snuggs in, covered with a tarp, close the back no see, no steal!
Pole saws just fit in along the side, snug up behind the drivers seat.
Leaves room for two people in the back seat, or a nice clean space for the groceries going home!
