1999+ Chevy Truck Reliablity
I'm wondering if anyone has advice or a good website that will state the common problems with the 5.3 and 4.8 drivetrains (sorta like the common problems thread here)...or if anyone knows from experience what sucks on the 1999+ GM motors.

I've owned MANY Chevy trucks of MANY vintages, in addition working in a Chevy service department whose main vehicle of repair was Chevy trucks (in addition to the performance cars).
I have been extremely satisfied with them and they've all proven to be trouble free. Don't let people tell you they suck because they have problem x and y. I have yet to find a truck that doesn't have it'* own set of nagging problems and to be brutally honest some of the problems the GM trucks do have pale in comparison to the problems ford and dodge'* suffer from. I'd rather work on 100 Vortec 5700 (the previous gen engine), intake gasket replacements than deal with Dodge electrical or transmission gremlins or ford'* transmission gremlins.
Our current Chevy truck (yea it'* not a fullsize), is a 2005 TrailBlazer now has 40,000 miles of trouble free service. The only problem it'* had was a A.I.R. solenoid that I had to wait 3 weeks for as it was on national backorder. I was getting a P0410 code and about an hour of troubleshooting it led me to the solenoid. I also had the stereo and HVAC headunits replaced as some of the backlighting had gone out.
Also what'* nice about the 99+ Vortec 4800, 5300, and 6000 is that they are nothing more than cast iron versions of the LS1, just in varying displacements. As such, they share a TON of aftermarket. So if you put 1+1 together, you can build a very stout little motor in your base model 2wd half ton Silverado and have a nice little sleeper.
