First, with 4WD you are not required to have chains, at least on CA freeways.
There is Caltrans requirement, that even with 4WD when you exceed certain weight, what I remember was about 15k lb you still need chains, so if you have heavy camper, you might want to check it.
Worse come to worse, I would not get chains unless you are really planning driving in deep snow.
Cables are much lighter, much easier to put on and much safer for the vehicle fenders, while will give you all the traction you might need in emergency.
I don't think the chains on the picture, with spikes would be legal on most of the freeways anyway.
