If it helps at all, I am pretty comfortable placing one crossbar in front of the limiter screw like in this photo here from when I mount my cargo box:I need to carry a 9'6" longboard on my rack ('21 TRD Pro with the FJ style rack). The farthest points to strap down seem a little close for this length board (for highway speeds) so wondering if anyone has tried adding another crossbar further towards the front

Must be fun trying to reach inside that cargo box. Wow, that is way up there.
Does it have to be mounted on the rack or can you transport it inside with the lift gate window down?
