We’ve been building this 1/10 scale camper trailer for a while now. It had a set of 1.9 wheels with our own custom axle design. We also developed a 3 axis hitch which allows full motion to the trailer link to the vehicle to allow for more tricky terrain.

With a couple of 3D printed scale accessories this trailer will look the part. You can even load it with your spare parts as it has a functional rear access hatch.
