Today I found out how effective it is. I was away from home and had parked on an uphill slope in a foot of snow. My 2wd truck just spun both rear wheels. I had a small folding shovel with me and half an hour of digging could not get my truck to move an inch. I got hold of a bag of salt and half a bag of salt spread under the two rear wheels did the trick. I had instant traction and was able to drive off.
I did not wait for the salt to melt the snow and ice. It makes me wonder if half a bag of gravel would have been just as effective.

Yes, more so. Kitty litter has been used for this purpose for decades.

How much did that salt cost you?
 
What were you thinking? You should not have a 2WD (RWD, assuming it's really a "truck") out in a foot of snow, particularly with hilly areas, unless you have studs or chains on. A bag of salt isn't going to make much difference if you have either of those remedies for a vehicle not suited for the environment. That bag of salt will not help a lot while you're driving... well, given enough bags of salt, in the back of the bed will help slightly, but forget I mentioned that.

I do have Spikes Spyders (tire chains) that I carry with me when I have to go out of town into rural areas, just did not have them with me today. A lot of the parking spaces were not usable because of people shovelling snow from their driveways on to the street, so I ended up backing into the one spot that was available and it had lot of snow. I should have parked further away, maybe the next street over.
 
I have Speedy Dry/Kitty Litter in a 5 gallon bucket. I keep it in my van in the winter for icy conditions when we're packing out of a job. It works great.

Seriously? I hope I missed the sarcasm here. I drove a 2wd truck year round in an area that had 150-225 inches of snowfall a year for YEARS. Studded tires are illegal as are chains where I was at the time. The best snow tires at the time were a Goodyear Plus 32 or something of the like, I couldn't afford those so the truck wither had Bias Ply Power King or Goodyear Xtra Traction lug tires on the rear and Goodyear Bias Ply Multi-miler ribs on the front. The last year I had it I was able to upgrade to a Firestone Town and Country snow tire. It did JUST fine in the snow, you just had to pick and choose your line, and where or how you parked it. Driving a 2wd truck in the snow teaches you how to manage momentum and handling a vehicle at the limit of the traction available. To this day I prefer being in 2wd in a 4wd capable vehicle at any speeds over 23-30, if I need 4wd to be going any faster than 30 I'm going too fast for conditions.

Yes seriously. That you aren't wrecking does not change the fact that the odds are higher as well as higher odds of getting stuck. It is not as though 4WD or AWD is a rare feature on trucks in particular, you are simply making bad choices.

Too fast for conditions has much to do with driving a RWD vehicle. Even a FWD, 2WD vehicle can go significantly faster, safely, in the same conditions as a RWD truck... given the same tires, on fluffy snow the FWD (car) may have street tires which aren't as good as A/T truck tires, but still wins in icy or hard pack snow conditions. This means that if you are driving safely, you're that guy holding up traffic.

"Choose your line" means very little if you have icy curves and hills. You'll still slide right off the road and slide to stops unless you live in a quite flat area, which in itself also tends to mean much fewer curves in roads because the road doesn't follow the cuts in hills.

It is utter madness to "prefer being in 2wd" and non-applicable. There were many options onto it being the norm for the past 20 years that vehicles that were 4WD instead of 2WD, auto-engage 4WD from sensing wheel slippage. If you're talking about an ancient manual 4WD system and there are some bare pavement sections then sure, but otherwise if you're going 23-30 that's a danger in itself because a lot of other people who can drive faster safely, will be trying to pass you, and if you're hogging that "best line" through the snow, you're causing everyone else to pick a different one to go around.

I am quite the advocate for "just drive slower" but in this case, you can do both, drive slower and drive a vehicle appropriate for the environment. 4WD/AWD exists more for exactly this, than people who are taking their vehicle off-road. The # going off road may be 1:1000 compared to those who drive in snowy winter weather.

I can use a wrench to pound nails and make arguments about how it works fine with the right technique, but that doesn't make it the right tool for the job.

I took the smiley face at the end as sarcasm

I usually drive my truck in 2WD, reserving 4WD for when I truly need it. Keeps me reminded of road conditions, I think. Although this one time I took an intersection a bit too hard and proceeded to go 10 or 20 yards down it completely sideways... goosed it too hard in a turn (and that was with snow tires too).
 
^ The smiley face was about a (significant enough weight to help traction much) load of salt in the back of a pickup truck, considering it is not something most will do and in an open bed, can become a wet mess. Back in the day I used to put sand bags in the closed trunk of a RWD car but vehicle options were fewer then, there was a greater % of weight on the rear end even without, and tire chains were legal at the time and were in the same trunk if needed.

I used to drive a RWD truck for work, putting on many miles a day in snow. Had no choice, company vehicle, and never got in any accidents but am very familiar with the trade-offs made and how they don't hold a candle to recent (2) decades of 4WD or AWD vehicles. Unless it's deep light packed snow I'd rather be in a FWD car with all-season tires than a RWD truck with snow tires.

Put simply, RWD truck is the worst choice (ignoring a street bike). Can it be done? Sure. It is a good idea? Not if you can help it.

Have seen people use floor mats under wheels to get unstuck as well. Makes me wonder if bring a small rug along might be better/cheaper than tearing up the floor mats.

You need to learn how to drive not just hit the gas and aim,
 
Can you explain to me how a 4wd vehicle steers or stops any better than the same vehicle in 2wd? My point is I can keep up with the flow of traffic in a 2wd truck just fine. I never said I only drove it 30, I said if 4wd was NEEDED to attain 30 mph or maintain that speed I was probably overdriving the conditions.

Your original point was essentially (and I'm paraphrasing) that the OP is a danger to himself and others for driving a 2wd in the winter. Which may or may not be true, but it's a bit of a gross over generalization. A 2wd truck can be plenty capable in the snow, I know, I've seen me do it.

Front wheels pulling you through turns helps control oversteer, having the front axle engaged increases parasitic driveline loss which helps with braking,

Don't kid yourself, 4X4 is superior in handling and stopping. Just because idiots drive 4X4 trucks like they are sports cars in the snow does not mean they are equal or inferior to 2WD vehicles.

When I was young, a friend had an XJ with snows. The difference between 2WD and 4HI was significant when coasting.

4WD, properly driven, gives you a better chance of matching your wheel speed to that of your vehicle when control is lost, making it more possible to sync the wheels with the road and regain control. However that assumes the driver is actively trying to do so, and not just dialing in more brake and more steering because neither are responding as desired.

By the way, you don't have to defend your 2WD usage to me. I rocked a 2WD Dakota for years before I got my 4WD. I took it places no 2WD was supposed to be able to go. For many decades, before the great truck & SUV craze of the 1990's, most of us had 2WD, and that often was the only choice beyond a few trucks. Somehow we all managed.

I thought sand was the right choice. I was under th impression that kitty litter, as a clay like substance, tends to wet and then get slippery as it shears on itself.

I'd choose sand or small gravel before I'd choose to use salt for a variety of reasons. And yes, it would have worked exactly the same as the salt did in the scenario you are describing. You just needed some "grit" to make it work. No way the salt did anything that quick to make it work besides add the grit...

And to be blunt, no need to defend the RWD/2WD thing. I drove a 2 wheel drive truck for years in the snow. A good set of tires and some weight in the back and it worked great. I'd suggest carrying some sand (like sand in a tube) and you could've helped yourself.

I'll also point out in the video above, what they are are showing works since it is apparent that the rear drum brakes are likely not adjusted correctly. With no ABS and full brake pressure in those circumstances, the rears should lock up - in the first test they clearly aren't, and you can't see it in the second. Being in 4wd forces that result with the pressure on the front brakes locking things up through the transfer case.

How that applies to a modern ABS equipped, disc brake setup is another story (or even anything with a non-part time 4x4 system). But I digress...

I forgot braking, as madRiver pointed out... 4WD simply helps keep the wheels fronts from locking up so easily, they brake better when they keep turning.
