I started with a Harbor Freight folding 4' x 8' trailer that had been sitting outside for many years. A good friend gave it to me to get it out of his yard. Free is always good! The tires and all of the wood were rotten so I up graded the wheel from 8" to 12".
I started by tearing all of the rotten wood off.
I disabled the folding mechanism, shortened the side rails, and moved the axle back 4 inches.
I added 2x4's to the front and back and then built the sides out so I could achieve a finished width of 5'.
Added 3/4" T&G OSB for the floor.
I cut the walls out of 1/2" OSB.
Attached the walls and added 2x2 spars for the roof.
Added plywood for the cabinets and shelves.
Trim for the outside of the walls.
Hatch framing and the latch.
Attached the tool box for the battery.
Cut out the doors and trimmed them out and installed the windows.
I made the windows open to the inside but in retrospect maybe not the best idea. I may move them to the outside someday.
Cabinet face frames and doors.
I also built some side tables.
Wiring run through the 2x2 spars.
Two layers of 3x4" foam insulation glued together for the roof. This allowed me to sandwich the wiring between the two layers.
3/4" foam insulation glued to the walls too.
Roofing installed. I bought 10' sheets and cut them in half so I had very little waste.
Test run to make sure it tows OK.
I glued Lauhala woven matting directly to the foam insulation on the walls and the ceiling with 3M spray glue. Then I trimmed it out with 1" bamboo strips.
Interior completed.
Galley completed including beer coaster bar top sealed with 2 thick layers of bar top epoxy resin. I covered the underside of the hatch cover with Tiki mask fabric.
I took it on the first camping trip to Mammoth Lakes.
All of the construction materials came from Lowes or Home Depot. The woven matting and bamboo strips came from Oceanic Arts in Whittier, CA. The fabric for the curtains, bedding, and hatch cover came from Islands Fabric in Carson, CA.
