This is a trailer with a folding roof tent I built to be hauled by my RC4WD D110 Defender.
The frame is soldered brass, the bed box is scratch built from styrene sheet.
The tent is lycra fabric.
A lot of parts and details on this are 3D printed and mostly designed by me.
Like the tent hinges, the fenders and the ladder.
