Hadn't thought about that location for fire extinguisher: do you carry a larger one in another location? I've worked a couple car fires that started as smoke coming from under the dash: not sure if that happened when I was driving I'd think to reach TOWARD the problem for the solution. Just my 2c.
What lives in the marine hatch, a gub? I know my dog would love the perch!
IIRC you have the rear seat removed, yes, so no issue tilting the seats back into where the rear seat would be flipped forward?
I haven't settled on fire extinguisher locations yet, I have one up front and one in the back but I keep moving them around trying to find a place I like.
The hatch has all the usual center console stuff: paper, pens, little plastic tackle box of small stuff, bag of change............ There is about the same amount of space as the OE console, just flatter.
And the seat is removed, but the cargo boxes fill the same space. When the seat is in you just flip the latches and the gas shocks take over. With the seat flipped down or the cargo boxes in, you need to flip the seat back forward, flip the latches and push on the seat slide handle. Then the gas shocks take over, pushing the lid up and the seat forward at the same time.
Takes a minute to write but only a few seconds to do. I think it is a reasonable compromise for the amount of storage it afforded.
All my tools fit very easily under the drivers seat with room to spare and the passenger seat hides a pair of V-bar tire chains, snatch block, shackle, tree strap, full first aid kit, armorall wipes, window wipes, hand wipes, bag of survival essentials and probably a few other things I am forgetting. And on top of all that, the latches are padlockable so if I want to leave the computer or camera in the the car I can lock them in there and slow down thieves a bit more.
