Shock talk-Bilstein 5100's or FOX 2.0 IFP
I have a 2007 chevy 2500HD classic CCSB 4x4. I am the original owner, and it is now at 112k on the original shocks. The truck still rides ok, but i'm sure new shocks would not be a bad move. I have it...

I think you are outside the envelope at 112k for shocks. I replaced my OEM at 140k, and the truck never had any noticeable bounce to the ride. It's not like the old days where you tested shocks by bouncing on the bumper and see if it keeps on bouncing when you let go. Modern shocks have multi-stage valving designed to control the ride at different levels.
I have basically the same suspension as your truck, and while I never got a bouncy ride I was noticing wheel hop over small bumps pavement seams, etc. I started looking at the Bilsteins and in the end decided to go with KYB MonoMax based on recommendations from folks here. A few bucks cheaper that Bilsteins and every bit as good IMO. From what I have read, Fox's reputation is built in the off-road market, which is why the shocks are rebuildable because of the beating they take in off road racing. Not sure how they would ride on the highway.
In the end, new shocks made the front end feel tigther because it eliminated the wheel hop I was getting, and also tightened up body roll a little so the truck feels a little more controlled over rolling pavement and especially with the trailer in tow.
It's hard to notice ride degradation since it happens gradually over time, but put the new shocks in and you will see what you have been missing.
