Back in 2014, I built a bed and folding table for my 2010 TC, but it took me 7 years to get around to making the space more useable.
Having to unbolt the bed legs (24 large wood screws in the floor) every time I needed cargo room, got old really fast.
It was the irregular shape of the walls and the double doors that had me thinking I couldn't mount the hinges to the wall. And I was right.
Then it hit me. "Put the hinge on the bed!" Duh!
A simple chain and hook holds the bed up, securing it to the wall.
Now I can easily lift the bed out of the way when I want to haul something, like my bike or sailing gear.
This is what it looked like in 2014.
This is what it looks like now.
I hinged the upper legs so they don't stick out into the cargo area, and I placed rare-earth magnets, under adhesive Velcro pads, to hold the legs against the bottom of the raised bed.
That way they don't knock on the wood as I drive down the road.
I made a little cut-out in the leaf so the leg on the left wouldn't interfere with folding the leaf against the underside of the bed.
The folding leaf is at the head of the bed, so a pillow goes there (when I even both to use the leaf), eliminating any chance that I'll feel the slot in the wood.
I don't know what took me so long.
