Chains on rear of class C

You should be OK with a single set, but check with DMV for your state.

We too must carry chains. Normal chains work fine. (Not cable ect.) We have had to use them a few times. And out side works fine too. Easier to chain up. But inside is OK just a pain to install.

Ouside duel only. Make sure you check for clearances.

That's not what it says in the pdf that you've linked. It says: "Single axles must be chained. (All four wheels with chains)".

I missed the note in the legend. Yes, both tires of duels must be chained on RVs

Is it worth noting that the (very helpful) link identifies these as "suggestions" rather than requirements-of-B.C.-law?

Outside dual usually. Run the inner dual up on some kind of block to give you clearance on the outer dual. Check your manual for type of chain required. For instance, my 2003 Ford requires type S chain which is thinner than normal chain. Not much clearance between duals. Here is a link for all laws in all states.
