In early Oct. I towed my 39' 5W toy hauler across WY on my way to Denver and experienced a blizzard. I found out why there are signs that say, "Bridges my be Icy." Driving only 35mph, I nearly jackknifed twice while driving up a fairly steep hill on bridges. I was able to minimize my rear wheels from spinning out by putting the truck in 4WD, and taking my foot off the accelerator as I crossed the bridges. I ended up parking the trailer in Laramie, and drove back the next day to pick up it up after the roads had cleared. This was the scariest experience I've had since owning 4 trailers over the past 15 years.
