I lost mine when the fitting that attaches to the boat cracked. I was going 35 MPH when mine broke and I never found the cover.Mine is up and in the boot but its a 20 mile trip once or twice a year to the marina and under 60.
X2...I always lay it down while trailering . The way mine collapses, I have to bungee the brace on each side to the rear cleat.
