All you have to do is jack up the front or back of the vehicle just so both tires just barely clear the ground, (some 4x4 vehicles have limited slip differentials front and back). Then all you do is manually turn one of the wheels, if they both turn together in the same direction you have limited slip, if one does not turn or turns in the opposite direction, you do not have limited slip.
That test does not work on 2003 and later 2500/3500's. You will need to have the vin run by the dealer or remove the cover to know.
To find out if the vehicle has limited slip differential, check the tag in the glove box. If the tag has the code DSA or says the gear ratio with the words limited slip, it does.
It is an option.
yes
It was an option.
It is an option, not all willl have it.
It would most likely not be in the base model.
The front differential is an "open" differential. No limited slip components there.
yes it is
75w90. If it has limited slip, additive is required.

I'm not sure what you mean by limited slip unless only a few? I have a 2005 dodge 1500 RT and have not seen another one like it. I was wondering if it was the only one that was made? I have tried to research this truck but come up empty.
As far as stock form, the rear could and the front would not. To find out if you have limited slip in the rear, one of the fastest ways is to look in the bottom of your glove box. Jeep put a notice sticker on the inside bottom of the box informing the owner of limited slip and safety information.
