But, its not street legal? So you have to first tow it to the off road area and then drive from the trail head? And either retrace your route back to the trail head parking to get your car, virtually limiting yourself to down-and-backs , unless there is a loop that brings you back to the tow vehicle.
Its a novel concept, no arguement here, but maybe not all that apllicable in the real world. Or atleast it may not have that big of a target market. The Bush's may like it so they can go camping on their own ranch.
