2WD GMC 2500HD

[MossRoad]

I live on a ranch and when it drifts, even 4wd trucks can't get through. The plows have to come through before people can travel again.

I don't know what all of this proves, one way or another. One anecdotal example that is contradicted by another anecdotal example proves what?

It proves that very few 2wd pickups in America actually had a set of chains back then. Very few. Yes, they were probably common in certain areas, but they are far fewer than "every". Most people we knew with 2wd pickups, and cars for that matter, just threw a bunch of heavy stuff in the bed or in the trunk in winter and off we went.

Now studded snow tires WERE quite common around here. My father had them for all of his vehicles up until the late 70's, and he'd have to have them swapped around spring and fall. I recall pretty much everyone's dad going through the same ritual.

How do you know this?

Here, you would be dumb to drive a 2wd and not carry chains.

Again...trading anecdotical examples is not proof of anything.

Yes, there you might. In most of the country, you would not. Hence "every" is not an accurate assessment. Half is not accurate. And 3/4 is not accurate. Very few in the big picture had chains.

Another advantage to 4wd trucks is the gearing you get with 4wd Low. I am always putting it in 4WD low to get up steep or go down steep hills here.

There is no transfer case giving mechanical advantage on 2wd.

I use 4 low a lot towing, real nice backing up a trailer. Used to leave hubs unlocked for 2LO with manual trans/lever 4x4 truck, gave something like a 16:1 R gear compared to 6:1

Still works with auto hubs and auto trans, just haven't done a 2Lo mod for the electric shift.

Also, IMHO,, you can not use Ford experiences to discuss Chevrolet.
The suspension it very different, and the frame stiffness is very different.
These two factors have a tremendous effect on 2WD traction.

Also, I was wondering if the OP's 2WD truck that is being discussed has a locking differential?
That also has a significant impact on traction.

I get into a locked differential situation once or twice a month,
and I grin when the truck "just goes",,

Hope it's not "made better" with computer.

I drove a 2wd GMC with a automatic locking differential, it would always spin both wheels until the computer shuts you off and you are stuck. Decent all terrain tires too.

Turning off traction control and even the "long press" on the button still doesn't shut it off??? Truck has been towed out of places a lawn tractor would have no issue driving on thanks to "electronics"

I made the mistake of buying a 2WD GMC a while back. I live in Michigan and got stuck the first snow and the sceond. No weight in the back end to provide traction. Eventually bought a set of winter tires and added a "ladder" frame of 1" PVC pipe to hold 4 - 5 gallon Home Depot buckets filled with sand. (Approx. 300#) which I located just over the rear axle. Was able to manage snow, and wet dirt roads pretty well, but with the extra cost, that I could have gotten the 4 X 4 option on the truck in the first place. Then I found out that the gas mileage on the 4 X 4 was only 1 mpg. less than the 2WD. Unless you're on dry ground/pavement and no snow, I would go with a 4 X 4.

I *think* all the G80 rears were “locking”.

Good point that you should buy what you need to do the job you need done.

I would bet that Texas has more 4x4 trucks than most states yet likely most of those trucks probably seldom leave hard surface roads. And until last winter snow was a non-issue here. I did fine in my truck on snow during the ‘snowpocalypse’.

That is a interesting comment I grew up in Montana and we had chains for our cars, trucks and tractors as did most of the people I knew.

Fast forward say +35 years and living in South Carolina I still have chains for both my 4x4s and even used them once here on the ice pull a trailer load of hay.

In my experience if the terrain is flat and dry a two wheel drive will go a long ways add weight / chains they go farther. However, throw a hill in the mix and and you are wishing for 4wd. Our place is hilly and I use 4x4 often. That said if I lived in a flat area I could get by without it.

A 4x4 with chains on all four corners will go a long ways before getting stuck too.

But when it does get stuck, it is stuck big time! Jon
