Replying to Hiding Spots in Toyota 4Runner?

I know a bunch of you have 4runners. Can anybody direct me towards a good hiding spot or two? I'm willing to make minor modifications, I just need somewhere very good.

I've been hiding small shit to the left of the steering wheel where the fuses are, but I can barely fit more than a grinder in there, and it's very obvious. Same problem with the area under the rear seats, plus I don't want to have to make people get out when I need to access shit.

Thanks, +K of course.
