How much vertical clearance does the installer need to get the gooseneck trailer and the storage shed onto my property?

The trailers are approximately 30 inches in height. The storage sheds range in height from the short wall utility sheds (102 inches) to the lofted barn with 3 inches of optional, additional height (139 inches). Depending on the model the customer chooses, the installer would need a minimum clearance of between 11.5 feet to 15 feet.
