I'm on my third 4wd truck in 27 years. Although I have always carried chains for the trucks and drag cables for my trailers, I never had to use them. I have test fitted them, but it has been so long that I should reacquaint myself before I need them. Typically there is no place I need to be that requires me to chain up to get there. If weather changes while I am away, I will take the easiest way home and can be prepared if it really requires chains.
Years ago, I traveled most of the Alps with a rear wheel drive Opel and no chains. There were some difficult passes but nothing that caused me to lose control going up or down. As posted, the wet snot in western WA and OR are much more difficult.
