yes, and i have the same type of bumper on my '07 Roo 23SS and NO! it's not substantial enough for a 2 bike rack, let alone a 4 bike rack. there's no bracing to it. the rear bumpers on ultralite trailers can only support a spare tire and it is right up against the trailer. bikes would be away from the rear of the trailer.
i own a lot of bikes, some of them expensive, so i researched a lot about bike racks and attaching them to trailers.
not one person said attaching a bike rack to the bumper of an ultralite trailer was a good idea. most had learned the hard way, by the bikes and rack breaking the square bumper off the trailer.
the only successful ones had a 2" receiver welded and braced to the bumper and the frame. the bike rack was put into the receiver.
