Small mod to my Gamiviti rack.
I wanted more surface on the rack, so I drilled and riveted three strips of aluminum.
Coincidental benefit:
There was a wicked loud vibration in the rack at about 38 mph that would make the whole truck hum. It's gone. Looks like the longitudinal strips broke up the resonance between the cross bars. I also think the high speed wind noise might be slightly quieter too, but that's less conclusive.
