You call that a hidden trunk? I keep a variety of tools in there. But in the hidden trunk I keep a jump box/compressor, and a pillow and some blankets.
I believe you may think of it as the well for the spare... but I don't see any point in running around with all that extra weight for something I haven't used in over 25 years... it's been a long time since I last used a spare!
I believe they are talking about the space below the floor, above the spare tire well. If I remember correctly the false floor is an option as is the spare tire.
I bought a bunch of storage bins from Home Depot that measure aprox 6"x12"x5"H and layed them in there like bricks. I put stuff like gloves, armor all wipes, jumper cables, extra diapers, juice boxes, the list goes on. Basically if I need the spare I only have to pull out the bins instead of a bunch of junk. Also that junk won't blend itself together making it hard to find stuff.
I'll post up some pics when I unload a bunch of tools from my hatch. It's been really cold every chance I get. Maybe today who knows. I think we are getting a solar vortex. It's supposed to hit 40 today.
