fender antennas

Having a tough time backing up an empty small boat or seadoo trailer, especially when it's behind a lifted truck that obstructs your view? Consider attaching some old collapsible RC antennas or fiberglass poles to your fenders - they'll collapse out of sight when not in use but extend far enough to give you a clear line of sight to the trailer.
