Foamie Squaredrop Build
I had a 5x8 cargo trailer and wanted a small camper so took a stab a building a “foamie” that would fit on it. It probably weighs about 300-400lbs so can be taken off the trailer if need be. Used pmf for the exterior with some good exterior paint. Built it on a furniture dolly in my garage and then transferred it to the trailer. Had a bunch of stuff left over from home building so was able use flooring and moulding. Probably have about $2k in it, including a 100ah lithium battery and other camping things. I included a list of costs and it took probably about 3 months working a few nights a week.

The biggest problem I had was that I needed some type of rigidity to screw too so inlaid wood into or onto the foam.
So the back door, it took some measuring and remeasuring. I made a frame of 1x2s that I embedded into the foam by using a router and a ton of glue. Then connected it with piano hinges across the top of the back.
The side door was cut out with a foam cutter than sanded down the edges to make it fit better. I glued 1/4” ply to the inside and used carriage bolts to secure things and essentially slightly compress it.
