For HD dual
wheel chains, you would require what is termed as "triple rail" chain assembly.
Each inner chain "rail" requires attachment as snug as possible and then the outside rail is cinched with the built-in camlocks or other slack eliminating device. (bungee type, etc)
This type of "Triple" chain can be mounted over the wheel/tire assembly after getting stuck and is the transport industry standard where winter conditions exist.
"Triple Rail Chains" for lighter vehicles would probably be by special order only. (most lighter duty vehicles do not have the clearance on the inside of the dual assembly for safely mounting this type of chain. contact your OEM for detail
On this site we are talking "RV" and we should generally not encounter severe winter conditions except in emergency situations. "Triple Rail Chains" for Dual Assemblies for an RV would be overkill.
For RV winter equipment, cable chains are light and easy to store. They will not stand abuse and are not something you can repair easily on the road, so if you are going to encounter winter condition on a regualar basis, carry an extra set.
