I own an 18' flatbed trailer and used that to haul mine from Kansas City to Wisconsin last month. I had no problems with clearance when loading or unloading, but I used my trailer's electric winch to load so I could watch the clearance and stop if necessary.

Getting the tie-down straps on the front suspension was a little tricky due to the low clearance, but by fully turning the front wheels in each direction you can get your hand in there and fish a strap through the lower control arms.

offdutyagain just hauled his new Crossfire on a U-Haul trailer from Florida up to Michigan. Maybe he will chime in with some additional info.
