Ran across this today when I got my new RV Tech magazine in. Seems to be pretty basic with the mombasa tents on top. They do sell a build it yourself guide as well as an unfinished version for around $750. Figured i'd throw it up here.
Our current trailer, the Explorer Box, is for the DIY home-builders looking for a lightweight alternative to building a Teardrop type camper. They are designed for pavement and maintained off-pavement towing, not off-road. Folks would normally tow an Explorer Box with a car or CUV.
