I think the GMC looks ok. I've done some chops and oddly enough it looks better as a RCSB than an extended cab.
I'm a little disappointed too, many options are not available on the rag cab like the uplevel interior, stability control, leather, buckets, pwr folding heated mirros wth signals, 6.0l etc. Still might pick one up, we'll see.
Interesting though, the GM ordering guide lists the 5.3 (same codes) as 315 hp, not 345. Not sure why. I am hoping the higher numbers are the correct ones. Also I am wondering how these engines will respond to forced induction...
