I have a 2010 Ram 3500 w/ Cummins and a 2009 GMC 2500 w/ Duramax and have never noticed a regen on either of them. Both have about 40,000 miles on them. I wouldn't know what to look for or if it would feel different while it's happening.
Basically, you'll see your fuel economy dip. Your RPM's when you're moving slower or idling in a drive thru will be elevated a tiny bit as well. My truck runs smoother because of regeneration but it certainly drops my fuel economy when it does hit. But it doesn't seem to hurt that bad and the few times I've observed a regen, they tend to last for only 5 or 10 minutes.
