Got it. So that helps with aerodynamics??Its a bit hard to tell, but the roof is slightly less wide than the floor. The sides of the trailer arent a straight 90 degree. They tilt inwards slightly.
The picture where the camera is looking in from the front with the rear door/ramp closed. Check out the 2 ski guides on the outsides of the ramp. They arent parallel to the rest of the ski guides and traction pads.
Heres a better picture from the rear. Look at the interior walls, you can kind of see they are tilted inwards. View attachment 2122131
