Spend the winter in the mountains.. with trailer.
Have CDL and drive 105k rigs...still. Retired LEO. Past DOT experience.
So with all that, take all this with a grain of salt. It is the internet of course.
True story on the 10k/chains required. Reality is, WSP does not enforce it on RV rigs. Note all the trailers and p/u's heading over in 4x with no iron strapped on when 'chains required'. I speak with a bit of experience on this. Still have a few friends that work/worked the passes.
Duals...? don't bother with the doubles. PITA, not required, and, did I say they are a PITA? Cables or chains both work.
I do carry drag chains for the trailer. Getting going isn't the problem... having a trailer pass you while stopping is the problem. It makes a bad day worse.
Happy Labor Day all.. NOW, it's time to go camping.
