So, what exactly do I have ?.
I sent a request to Dodge for a copy of the build sheet for my 2000 Dodge Ram, so I could find out what gear ratio I have and if its limited slip or not.
This is what I have, corporate 9.25 LD rear axle, 3.55 rear axle ratio.
So is this limited slip or an open rear axle ?.

The best way to check to determine if you have a working limited slip unit in your rear differential is to jack the rear up so that both wheels are off the ground. Turn one rear wheel forward - if the wheel on the other side also turns forward, you have a working limited slip differential.
The dealer can also tell you what options it came with from the factory, by providing them with the last 8 digits of the VIN number. If you call 800-926-8254, they can tell you. Also, keep in mind that the possibility exists that someone may have modified the rear.

Q; When testing to see if you have a lsd or a open diff as posted above what should the trany be in when doing this test?
A; Both tires turn in the same direction when they are off the ground and in neutral. In park they spin opposite directions, but it takes more force on the wheel to do so.
How to test an Trac-Loc as per the 2001 FSM page 171
DIFFERENTIAL TEST
The differential can be tested without removing the differential case by measuring rotating torque. Make sure brakes are not dragging during this measurement.
(1) Place blocks in front and rear of both frontwheels.
(2) Raise one rear wheel until it is completely off the ground.
(3) Engine off, transmission in neutral, and parking brake off.
(4) Remove wheel and bolt Special Tool 6790 or equivalent tool to studs.
(5) Use torque wrench on special tool to rotate wheel and read rotating torque (Fig. 31).
(6) If rotating torque is less than 22 N·m (30 ft.lbs.) or more than 271 N·m (200 ft. lbs.) on either wheel the unit should be serviced
