I agree with Chris, most canopies I've seen, including mine are slightly angled up at the front and can catch the wind easier than if it was reversed. I couldn't load my tractor backwards because of the weight issue but have hauled it much at speeds of 55 - 60 mph for shorter distances. When I loaded it up to haul from Fl. back to Tenn. here I took the canopy off though, I didn't think it would be safe at 75 mph and with gusts from semis it could easily have folded her back. Mine has an excellent angle iron frame and good solid mounts to the ROPS and a heavy gauge steel roof but it's not indestructable.
