That build lasted a few seasons, although I didnt really have a solid idea of the layout I wanted, I just started building.
After a couple iterations of that "layout" I went for a different approach, having a single wide bed on the passenger side and cabinets on the driver. I converted the hinges from a westy for the couch/bed.
This layout allowed me to have a "singles" bed, and isle to get to the back area as well as ample room to get to the cabinets. As a note, they are sized to fit milk crates so I could just load up food etc in the house, and easily move them to and from the van.
I upholstered the couch with really nice foams ( I broke my back, yet it sleeps great )
I started the galley to hold a electric fridge, microwave, and Portable A/C. ( I vented it through the driver window for a season) It was very nice, and worked perfectly for that year.
After a divorce, and camping alone for years, I decided that I would need a "double" bed from now on. So I started playing with modifying the setup I had, by moving the couch toward the middle and filling the passenger gap for storage.
I ran square alum tube along the sides to support.
That setup worked, but I didnt want gaps in the foam, due to my back, so started looking for a more modular way to do the bed. I should not that I have a fairly firm idea that I should be able to remove the bed very fast and easily as I have always used the van to carry farm items (until recently) like Pumpkins, cut beetle kill ash wood, etc.
For the last few years, this has been the setup, which works really quite well. I spend at least 4 months a year in this setup, and have been finding the shortcomings of it. Namly, I need it easier to get to a few of the storage cabinets, since the foam bed is kinda in the way. I need easier way to get under the bed. As that stands now, the platform is really cool, and hinged in a way to pull up out of the way , have an exteded part for the bed length, and allow access to the underneath. It just needs to be tidied up a bit. And the main thing I need is a top, so I can stand up, did I mention I broke my back?
