That being said. I'm drawing up misc plans on what I could perhaps build. The one I have been thinking of the past couple days is pretty much as the name goes, 'Bed in a Box'. It will quite literally be a 4x8 3/4" plywood box on an HF 1720lb trailer. A door and window on each side, barn doors on the rear. A tongue box would hold all of the electrical.
Under the floor will be approximately a 4-6" deep storage area. In the middle will be space for my 2'x4' folding table to slide in. To the side of that will be a place for two fishing rods to stow. These can be slid out by opening the back doors. Everything else will be empty storage accessible by rolling the bed foam back and lifting the left or right side of the floor; it will simply hinge in the middle and lay in place.
In the rear will be storage for my 5 day cooler on a slide out tray with the remaining space perhaps used for a fresh water container. The top shelf will perhaps hold a microwave, maybe our little Coleman stove, and some dry goods.
Inside there will be a shelf 1 foot from the ceiling, extending perhaps up to 18" out. This will probably be for some duffel bags. A Fantastic fan would be in the ceiling in the middle along with a dome light nearby. Probably a few hooks along the walls up high for hanging things. I'm thinking a reading light on each side. There would be a 110V outlet at the foot board and head board. 12V outlets at the head board, maybe at a small shelf in the middle of the forward wall for holding a cell phone, etc.
There would be an extra plug in at ceiling level for the addition of a small wall mounted fan or a ceramic heater, as needed.
Outside a porch light at both doors and 110V outdoor rated outlets on both the left and right side, perhaps above or just ahead of the fenders. A stainless hook by both doors for hanging shoes or whatever else.
I would like to design a custom awning on each side that would roll out for a little cover should I not want to setup a bigger 10x10 at the time. I figure I could do this easily with some PVC pipe, a couple custom made vinyl sheets, some drip rail, and a little creativity.
A tongue box would hold all the electrical stuff, extensions cords, a portable radio, and whatever else I fancy. The shoreline connection would be mounted on this box, too. I'm thinking about putting all lights on a wire less key fob to make electrical wiring alot simpler (no switches everywhere) with a simple override switch for everything inside the box should the fob be lost, broken, dead, etc.
Paint, probably a simple white with appropriate Saints, LSU and Chevrolet Bowtie decals placed accordingly

Here are my super sweet drawings I came up with. Eat your heart out, computer programs




Feel free to criticize, question, add to, take from, etc. I'm just brain storming because I'm considering building a tiny trailer, so this may not be a final plan by any means. This one is a very utilitarian build that has maximum space and very simple to build...I mean c'mon....its a BOX, lol!
Cyall!
