I built a cabinet door contraption.
The cabinet over the refrigerator is where I store miscellaneous kitchen stuff. It's always been awkward to get into, for a few reasons. The door was hinged to swing upwards, and in a narrow section of the van, so you sorta had to crouch sideways to avoid hitting yourself in the face with the door.
Then, because the door was hinged to swing up, it wouldn't support itself open and would sag in front of the open cabinet, necessitating propping the door on top of your head to dig into the cabinet.
Also, in order to accommodate the hinges, the designers used about 5" of wood at the top of the cabinet, concealing 5" of precious usable cabinet space!
Here's how it used to look...
...and here's how it looks now. I simply built a sliding door portion. It's not finish quality pretty, it's just way more functional and it cost me $9 to build. It latches up securely, is easy to unlock, slides down totally out of the way on those side rails, and at top I have only a 2" rip of wood for the frame, meaning I have an additional 3" of usable cabinet space.
