I helped one of them chain up his truck after he, myself and many others spun out on the Marquam Bridge in Portland, Oregon last winter after a couple cars hit black ice and crashed, causing traffic to come to a stop on the incline. I was right behind Stryder, after throwing a set of singles on my drive axle I got back into my tractor and proceeded to watch the Stryder driver struggle with his chains, so after about 10 minutes I realized that if I wanted to get going anytime soon I would need to help him. Once I got up to the truck I realized three things:
1. Driver knows limited English.
2. Driver has limited experience installing chains
3. Chains appeared to be built for ultra low profile 22.5 tires, not the 11R 22.5’s he had on the drive axle.
With some jerry-rigging (long story) with bungee cords I finally got the chains on well enough to get the truck up to the top of the bridge at a slow speed, which the driver did.
I see them quite often on I-5 in Portland Ore, I can’t recall seeing one of their trucks south of Salem, Ore, but then again my line run is at night so my vision is limited. That’s all I can offer.
