This is my first thread, so I'm going to screw it up. Bear with me.
This past spring, with the help of a friend with a lot more woodworking skills and a lot more tools, I built a sleeping platform in the back of my 2005 V6 Limited. I modeled mine off of g3ran3t's posted here:
Looking for plans..Rear Storage to fold out Sleeping Platform? . My goal with this thread is to show others that you can sleep in a 4th gen if you are 6'2".
I was working on a compressed time schedule, as I was leaving for a week+ long cross-country road trip with my girlfriend two days from the night we started building. My primary goal was to have a functioning sleeping platform that could be disassembled into two halves easily.
Since I am 6'2", to have enough space to stretch out I had to slide my front seats all the way forward and tilt the seat backs upright. The platform extended up to the back of the front seats and rested on the center console as well as on a screw-in wood leg at either front corner. Just as g3ran3t's, my platform was two major pieces: 1) the strong aft section with the drawer (mine actually does not have a drawer) that extends from the rear hatch to the back of the rear seats and 2) the front piece of plywood cut lengthwise into two halves and held together by a set of hinges so that it can theoretically be folded for storage ( I screwed this part up). The front section and the top of the aft section are both covered by cheap "carpet" I found in the paint section of Home Depot for maybe $12 a roll. I was in a rush and covered the entire front half in one piece of carpet via staple gun. This made it impossible to fold and for the entire road trip I left it unfolded and slid it back and on top of the rear section when we were not sleeping. The front section is longer than the rear section, so storing it this way during the day was not ideal as we could not unfold the rear seats to their upright position, but it worked for the time being. When the front section is not inside the 4runner, the rear seats sit upright easily.
A warning: If you staple the carpet to the underside of the platform, the staple heads can be dangerous for your interior. I managed to scratch up the interior trim on top of my wheel wells pretty good while sliding the platform in and out.
Hope this helps anyone doing the same kind of research I was doing last spring.
