^^^ It's definitely not limited slip since gm never put limited slip diffs in their trucks.

It could have a locking diff which is rpo code G80.

Seeing as the condition seems to be mint, I would not sell it. I would personally either leave it 2wd and leave it how it is. Or put good, slightly larger tires on it and a locker of not already equipped and keep it nice.

Then, there the option of a solid axle swap. But then your looking at quite a bit of money and in my opinion, a less drivable truck (unless done perfect)

You could also buy a cheaper, older 4x4 truck to drive when the weather is bad. Gmt400 trucks are usually a dime a dozen.
 
In any gm TRUCK it's either a open diff or a locking diff (G80)

Gm CARS have a G80 as well which is a limited slip posi diff.

So if it's the stock diff it's either open or locking. Gm has never put a limited slip in a truck.

A lot of times people call the G80 in their trucks a posi or limited slip. And they are wrong. It's a true locking differential.
 
No problem. Reading my post it sounded kind of rude. It was no intended that way hahaha.
There is always confusion on the G80 rpo code since depending on what list you look at it may say either locking or limited slip.
