that thing is cool,,,,, In my Tacoma I built up the floor 2x6's then covered with hinged plywood so I could have a lot of compartments to put stuff in and still have the bed, I have a stove and like to climb in the back and cook when taking breaks from hunting and fishing but was keeping an eye out for some kind of bed that would work to take quick naps and this might be it,,,,,, I'm thinking eliminate the lower one and keep the higher one where it would be warmer,, or use the lower one in the summer only..
thanks for posting.
