2014 Rav4 Sleeping Platform and Drawer - Keeping Rear Seats

I built this platform this spring in order to make it easier when road tripping and car camping to hold all my equipment. Total cost was $108 USD, all items were purchased at Home Depot and I had them cut the plywood pieces for the platform as well as the three plywood supports. Other cuts (for the 2x4s and drawer) were done at home.

Dimensions: width: 43 in, rear box: 29.5 inch, extension platform: 30.5 in, headboard: 11 in. Entire length: 71 in x 43 in (plus a bit for the carpet width). Flip down headboard could be built another 5 inches longer for taller individuals if the front seats are pushed all the way forward.

I looked at a number of different ideas throughout my decision process and build. The base/rear box of the platform I initially modeled off of this video and attached blog post (although I used 2x4s at the rear to hold it together rather than plywood and did a 2x4 at each vertical plywood piece to increase stability):    • Sleeping platform for in my car, 29se...  

A lot of Rav4 builds I've seen leave the back box portion open so they have easy access to the spare tire, but since I wanted to have a drawer this wasn't really possible. I kept the drawer smaller and to the right side where there is the single seat is in order to keep a clear path that would be long and wide enough to house my skis and snowboard. I live in the Boston area and wanted easy access to my rear seats so I could still carry passengers--thus it was necessary to create a product that was removable and could sit on top of the box in the rear trunk area.

Update (Fall 2019): I recently posted a breakdown with the specific dimensions of my build and photos of the process here: https://rav4build.wixsite.com/website...
