I was fascinated by the trailers used by a Maine firm to deliver two sheds and a garage to Hodgdon Road. They had two sets of wheels for highway travel. That’s normal. BUT, in addition there were two short axles perpendicular to the highway set, with four more wheels, which allowed the trailer to move sideways. A pedestal allowed the load to be turned around, front to back. All was powered by hydraulics, which also tipped and delivered the buildings with precision. Got into some really tight spots in my yard, as seen in the photos.
