Okay - so yesterday I transferred some of my items from my old winter car to the Subie wagon. Put my little first-aid kit in the wall compartment by the hatch opening. Put work gloves in the other wall compartment where the jack is. Then I pulled up the carpet floor and tried to put my little toolbox kit in that storage tray....NOT. I tried every which way to fit it, but the compartments are not large enough. Then I pulled the tray out and tried to put the toolkit on top of the spare tire. Still wouldn't fit - it stuck up a little too far so the tray wouldn't sit flat when I'd put it back on top.
So I ended up bungeeing the toolkit along the side wall using the front and rear tie-down latches to anchor the bungee cord. All I was able to put in the storage tray was a thin blanket.
So....do YOU use that storage tray, and for what?
