One common theme here is in my opinion single chains are useless, wrong set of tires being chain should be front axle or all 4. Not to mention the extreme lack of training. Have been class 1 driver 30 years so I feel i understand. Should be a minimum requirement to run mountains also chaining up properly. I seen alot of episodes now, lots of super B's with single chains which as far as I know is against BC regulations. The main thing I see and do not know if regs allow or not but zero trucks in the episodes i have watched have a steering chain on. I just dont understand alot of this stuff chaining up a truck properly is imperative. I was always told if you think you might need chains then probably do.
