Chains? From Butte Montana at minus 30 degrees over the Minada Pass at 3am in a true blizzard I've never chained up a four wheel drive. Of course I don't have street tires and I don't drive like an idiot. In the back country high in the Sierra Mountains well off the paved roads it's called "wheeling". Everyone who is there is "aired-down" to the maximum without popping the "bead". Anyone entering the area caught with "chains on" are delt with. Their chains are cut-off with bolt cutters. Yes... there have been many angry words of exchange. Funny... no cell phones work that far back into the mountains and calling the Hiway Patrol won't work. The "new buffoon" learns from the Anarchy-crowd how to conduct himself in the snow. Aired-down, you get up on top of the snow and pack it. You tip-toe along like a ballerina and never,never dig holes. Tread lightly is the law of the land... speed is not the quest... safety is.
Chains are for the inexperienced and faint of heart average driver who doesn't have a clue. The Hiway Patrol has no time to deal with thousands of idiots (look at Interstate 80 east of Sacramento) on a snowy Friday evening before a big ski weekend. I've been in all the situations but, I've been taught by some of the best on how to survive and drive.
Not to offend anyone here on the TDR but, if you chain your 4x4 CTD you lack some common knowledge. Chained up will take you quite a long way until you dig in so deep you're bottomed out and you then deserve a good slapping. Airing down with an ARB up front will take you much farther... if your heart will hold out. These trucks will exceed the "fear factor" of most people who own them. Get with someone who knows... it will pay off in the long run.

I like what you said here, actually. A little brutal, maybe...

I have also never had to chain my Dodge, ever, in
any conditions until last week, including tons of winter mountain driving in the NW (I'm a snowboarder and we call our snow "Cascade Concrete"). I've just kept really good tires on her.
Last week I had to chain. My driveway goes up to a cul-de-sac that continues up, and there had been no plowing or sanding. No problem until the 1+ foot started to melt and my
well-worn tires wouldn't take me past my driveway. Even chained in the front (no steering without them) I had to use
4 low (oh, THAT'S what it's for!) and just
let 'er idle to the top. Worked like a charm!
Not everyone has snow experience and I don't blame anyone for wanting to be cautious. The chain manufacturers say put them on the rear on a 4x4. I've never seen chains
required on a 4x4, so I'd say the key is to
have great tires, Mud and Snow type such as
Dick Cepeks , and carry chains and a little shovel just in case. Follow someone you think is driving within your capability, be easy on the brakes, and remain calm.

If you get stuck (which you probably won't), you will be able to get the chains on where you need them.
