I elected to replace the shocks because I noticed too much porpoising and multiple oscillations with big dips. Also, one of the tag shocks is visibly broken. The bushings where the shocks connect to the frame are all multilated. It was a big bill, but I am in the honeymoon/ pimp it out stage with the new coach and all of you know I am OCD about handling.

You can take the shock loose from one mount and do a field test. If you can slowly move it with all your might, then that's about what a new one feels like. If you can move it easily then it's bad. I am just echoing what Steve said.
