This project started out as a trailer that I built on speculation, perhaps, to be sold as a prototype kit.
I sold the"kit" to a customer that wanted me to finish it.
I built it as a 5-by-8, along with some custom features.
Here are the major components,
There are side panels, floor and bulkhead frames.
I built the floor for a 5-foot wide frame that I already had in the shop.
Here, I'm adding skins to the bulkhead frames.
I used 1/8" ply to save weight.
The exterior is 1/4" Oak ply from Home Depot, and Cherry, left over from the 'Rondack Lodge.
I decided to build the spec kit with crank out windows from Grant Whip.
