Made a vid of building a cantilever roof rack to overhang the front

Watch at YouTube

Same principle for any ladder rack with overhang.
This one is to carry the pole system roof trolley.

Sorry . . . you can't call that a cantilever rack.
It's supported at more than only one end.

Technically, the overhang part is "cantilevered" but that term does not apply to the whole rack.

. . . . nice build either way . . .

Yes if you are referring to a building with a cantilever protruding from the side of it.
But a Cantilever just describes what is forward of the front support, which is the section the cantilever begins at.
The rearward facing rod just ties it off the same as it being attached to a wall.
The wall is the vertical rod.

Yes the whole rack is not cantilevered, but then neither is a bridge that sits on land at each end.
A bridge has a cantilevered sections but that doesn't apply to the parts at each end that sit on land, never the less its still a cantilever bridge.
If the whole bridge was a cantilever then it would not sit on land, and then it wouldn't be a bridge.

And Zinc plating.
So cheap, no prepping they just hot tank it, takes 2 days.
I just take everything I make in steel to them now, don't bother with paints and powder coating anymore and far less sand blasting..
I found a guy nearby who has 4 metre long tanks and can do long stuff like this.

Cantilever means the same thing no matter if you're talking buildings, bridges, airplane wings or roof racks.

Cantilever - - a rigid structure supported only at one end.

Yes, it is supported at one end being the front support of the vehicle where it overhangs, what's rear of that is irrelevant.

So we're saying the same thing.
