I’ve driven 4X4’s up here in Canada ( BC mountains) for YEARS and have never ever had to use chains on the Hwy. And where I live you can’t get out of the valley with out going over Mountain pass.
If the law requires you to have them, that’s one thing......do you need them, I highly doubt it.
I also have a NL camper and drove out of here two winters ago on my way to AZ in a snow storm, I used 4 wheel drive but never needed or came close to need Chains.
Just get something that will fill the law requirement, you will most likely never use them on the Hwy.
Soup.
