Last summer while we were traveling around in Francis I never bothered to make a sleeping platform. The FSJ has a really ample cargo area once the seat is removed so it never really became a high priority for me (also, my living situation last year never really was conducive to building one). When I brought Ruth home, I knew that I would need to build a platform in order to have well organized road trips. The platform didn’t get built before my Thanksgiving trip to Arizona but that mostly just proved that a platform would be key to being happy—packages of bagels rolling around on the passenger floorboards and weird lumpy unlevel futons are cool for a couple of days but SP and I sleep in the Jeep often enough to justify something better.
The first iteration of XJ platform I used was on my first big US road trip in 2010. F and I made it out of 3/4″ sanded plywood. We didn’t want it to sag or be unstable but we later realized that we’d way over built it. F passed along to me some measurements for a more streamlined platform out of 5/8″ OSB. His new version had made some cool improvements that increased access underneath the forward part of the platform and I decided to mostly copy his plan.
I picked up a sheet of 1/2″ OSB and had it cut to length in the store (Lowes and Home Depot will both do this for you) as well as twelve 1 1/2″ L-brackets (they came in packages of 4). Back at home, I cut the remainder into supports: three lengthwise supports and a cross-brace for the front. I rough fit everything together inside the jeep to confirm placement before screwing things together. I decided to trim the back corners to 45-degrees for ease of reaching things that might fall to the sides of the platform and to nestle the platform as far back against the tailgate as possible. (I’ve got long legs and drive with the seat just one click forward from all the way back.)
I decided to leave the plastic trim at the bottom of the tailgate opening on, although in the original and F’s recent version, it was removed for ease of removing plastic storage containers. (I can always decide to remove mine later if I decide.) My outer supports rest right against the base of the wheel wells and the middle support is aligned with the tailgate latch. The front cross member is centered and rests on the narrow lip that the front of the back seat bottom rests on.
Everything was assembled with the L-brackets and put back into the Jeep to check for fit. Once I confirmed everything was in the right spot, I took the platform out one more time and used my angle grinder to remove the points of the screws that were protruding. Coats and sleeping bags don’t play very well with sharp pointy things so it’s time well spent.
The platform only took me a couple of hours to build and really affordable:
◊ 1 sheet 1/2″ OSB: ~$10
◊ 4 packages of 4ct. 2 1/2″ L-brackets (the Stanley ones I got included screws): $13.27
Platform total: <$25!
(I also bought four plastic totes from Home Depot to organize my storage for another $20)
Depending on your desires you could purchase thicker OSB or even plywood if you desire a smoother surface. I’m going to test this out for the summer and see how it goes, the rough surface might wind up collecting more Sprocket dirt than I want but if I change my mind, I can disassemble this and reuse my brackets so it’ll be a good experiment.
