My last greenhouse was made by our local shed tiny house people, and delivered just like that and moved with a mule. Fun to watch when it was set up. Mule and skidster tracking are a pain in the butt to keep the tracking clean when it's muddy and freezing up, neighbor Marlon was just over the other evening hosing his skidster tracking down on our cement by one of our barns, so it wouldn't freeze up.
