I've search past threads concerning the different options for the subject racks and have a question. In many of the pictures posted in those threads, it appears that the bikes (or portions of them) extend to or above the roof line of your 5th gens. Is this the case, or are the angles at which the pictures were taken a bit deceiving? I am looking for a hitch mounted rack in which the mounted bikes will fit comfortably underneath overhanging canoes and be worry free of contact from an occasional "bounce". What racks seem to keep the bikes mounted below the roof line? For reference, I'm talking about mountain bikes with up to 150mm travel forks.
