Flinstone Floor?
So is it normal that I feel like the floor of the cab is made out of plastic? I.e. I can hear every bump, stick, sound, pebble and I feel like I can stick my feet through and pedal the truck! Since I am listening intently to everything to get used to the truck, it's just a different feeling then I am used to. It's like I can feel the axles, driveshaft etc, turning beneath my feet -- on one hand, I feel in tune with the truck, on the other hand, I feel like there is nothing there!
Also, speaking of sounds, does the turbo whistle get higher in pitch as RPM's increase?

I don't think I hear any popping. I don't mind the noise too much, since the engine is already pretty loud in there, I just wanted to make sure that everything wasn't supposed to be silky smooth. I have noticed that when I am stopped, say at a light and then it turns green and I pull out, that there is a slight feeling of a soft clunk (not audible) like it is dropping into gear or something. Hard to pinpoint where it is coming from, maybe something just needs a little lubrication? It is subtle, slightly increased when pulling the horse trailer. I think it's from the rear end, but I wouldn't bet the farm on that guess.
Is there a procedure (visual, wiggling?) to check sway bar integrity?

Hook it, I'll pull it.

This may be your clunk on take off. click here
For the sway bar, look at the bushings to see if they are coming apart. You could also take the end links off and tie up the bar, then drive around and see if there is a difference.

Another vote for swaybar bushings. Mine were pretty shot and I pulled everything off only to find that the bushings I have aren't correct 
so I'm running w/o the front bar right now. Much less "floor noise."

My guess is the sway bar bushings, but it's also a good idea to check the splines in the driveshaft that Rick posted. Use locktite on the bolts when re-installing the driveshaft. Real bad things happen if they loosen up!

Thanks miller for the great visuals on the rear end greasing (hard to type that without giggling). Does anyone have a picture of what the sway bar bushing are supposed to look like (visual learner here)?

sway bar bushing are a 10 minute fix. You wont know they are bad untill you get the old ones out. I bought regular moog parts for 10 or 15 bucks at local autoparts. I did mine with just hand tools. Another truck I work on had a similar noise issue, ended up being missing exhaust manifold bolt on drivers side rear. Had been missing for some time and most of the gasket was gone. Then there was also a huge hole on the firewall, must have been from plow controls or something. I still dont know why the hole had to be so big. After fixing the manifold and plugging the hole, the truck is MUCH more quiet, even with the still bad (very common) sway bar bushings.
Another thing I changed on my truck is the sway bar end links. Mine, at 250,000 miles, were worn out and made noise when you shook them like a baby rattle. Again, another fairly low cost and easy repair.

Hmmm, well the bushings might be covered under my warranty, but lubrication might not. Must investigate further. I think y'all are right on on the rear end lube, I was listening to it on the way home from work and it is definitely in the rear end right as it drops into gear.

The sway bar bushings will be hard to check visually yes, but the end link bushings are easy to visually check. Crawl under truck, look at end links... there shouldn't be any metal to metal contact between the end link and the sway bar.

Ok, will check -- it's hard to get under this thing, my first truck ever that is not 4x4 and my driveway is lumpy gravel, should be entertaining.
And it's driving my crazy that my thread title is spelled wrong and I can't fix it...
