Can't help you much, as so far purchased all my Big Red accessories from Honda. However, sure wish someone would come out with a substantial roof for the Big Red, or at least some aftermarket auxiliary clamps. The factory top flutters a lot when being towed at highway speeds. The instruction say to take if off when transporting. Yea, right! Easier said than done. What have the Honda design engineers been smoking? When towing I wrap bungee cords over it, but this looks tacky.
