Just for the record, unless you live up in the mountains (Denver is not there, it's in the flat plains of the state) we don't get much snow. I totally agree with your plan, but it never happens. These trucks suck on just iced-over roads, and need some snow depth to get a grip, which is exceedingly rare. When I moved here I assumed we got tons of snow, but have been really disappointed (I love snow!). If the opportunity comes, I will definitely do it though, complete with a giant pot of hot chocolate brewing in the back!
Funny story about it though. Growing up in Cleveland, I would regularly take my big offroad trucks out in snow storms to help pull people out of the stuck. We've only had one storm in Denver, in the 12 years that I've lived here, that was actually impressive, which was about 36" in 24 hours. I went out in my '79 K5 Blazer with 42" tires, like I use to, to pull people out. However, what became apparent is that because it snows so little here, the towns don't own many plows or other snow removal equipment (and they don't use salt like the NE USA). I looked it up once, and the city of Denver, roughly 150 square miles, only had about 50% more plows than my home town in Ohio of only 4.2 square miles. So the plows could only keep a handful of the main streets in town plowed, leaving side streets 3' deep with a 4-5' berm from the plows. I ended up spending the whole evening pulling vehicles OFF the roads, that had managed to get onto the driveable streets but could no longer get onto side streets.
We just get the reputation because the mountains will actually get a few feet at a time, and all the invading Californians live in the plains of Denver and think every flake that falls is the snowpocalypse.
