I have two CD-80 road racks. One is gray the other is black. The gray on says SV. The black one does not even say strand on it. The Gray one takes a different style of plug in card than the black one. The soco connectors are also different. Which rack is the most up to date version? The black or the gray. I haven't dug into them very deep to find dates yet. Also i strongly recommend NOT CARRYING A CD-80 RACK IN THE BACK OF A PICKUP, EVEN IF IT IS A 1TON DUALLY. It makes for a very scary experience.
