This was a good thread to read. I picked up some good tips and my winter setup is now complete.
My truck sucks for winter: 1991 ranger (old), 2wd with NO limited slip, regular cab with no weight distribution over the rear wheels, etc.
Here's a pic of everything:
I built a 2x4 wood frame, it has 240lbs of the "Quickrete" sand bags, and the shovel is mounted to the frame via hooks, and secured w' a bungee cord.
