Please give details on your 392 sleeping platform.
Wife was actually the instigator. Wanted to camp (knowing rain would happen), but stay dry and not have to put a wet tent away in the morning. I have seen other sleep platforms where they put drawers under the bed, but the idea for us was just to sleep, and carry minimal gear for the weekend. Thus, we just wanted a flat platform to place our pads and sleeping bags. We do hit the hard trails, so this had to be something we could strap down along with the rest of our gear. It would help if we had a roof rack. (That is decision is in the works... so difficult to find the right one for our needs.)
Background - This 392 is my wife's daily driver, I have a kick ass Ford Escape as a company car (read in sarcasm).
So, this image below is a total optical illusion. This platform is perfectly flat. I used some scrap 3/8 inch plywood and some leftover 2x4's and 4x4's from a house project. It is mega solid, doesn't shift, it was literally perfect. It comes apart in 4 pieces to slip easily into and out of the Jeep.
I first made section C. It is 3/8 inch ply screwed into 3 4x4's. I then cut section D which has a 4x4 piece screwed into it to slip between the forward and aft 4x4's of section C. I then made section B, which is screwed to a 2x4 in the front and towards the rear, one on the 4 side (towards the back to match the 4x4 height), and one 2x4 on its side at the right height to support under the slope of the seats which are simply laid down. This sleeping set up is made to incorporate the rear seats just laid down, head rest and all. Slide the front seats all the way forwards.
Then section A was made (closest to front of Jeep) to overlap section B.
We tried it out, and it was perfect. Perfectly flat, did not shift when sleeping. On top of the wood we layered a nice sleeping pad and an old thick cotton sleeping bad as another pad. Then our sleeping bags on top of that. It was so warm in the Jeep (low that night was mid 40's) and that was with two windows cracked a quarter inch. Condensation still wetted every window inside. We slept great.
When I got home, we decided this was a keeper, so I found some leftover paint to paint each section and had some high density foam sleeping pads I cut to each piece and stapled on each of the 4 sections. When put away in the basement, stacked they take up little room and look like this.
If you want more pics or details, let me know. Our next move is to get the right roof rack. I am considering the Mule Expedition at the moment, just so stupid expensive for a bolt on (no drill).
With a roof rack we can throw the light stuff up top, have something to tie a tarp to for sun/rain shade, and very important for what we do, put 5 to 10 gallons of extra gas up top for remote trips.
We will most often tent camp, but this inside option is very cool. My wife is cool. She finds it fun.
