Some people automatically think more $$ equals better. Personally I prefer my black SLT to the TT Laramie, but that's just me. The Laramie is a great looking truck, but I don't necessarily want my truck pretty, if that makes any sense. Mine came with the Alpine audio system, bucket seats, turn signal mirrors, the tow package and most importantly the HEMI!!!.
The main difference I think are some interior trim crap (wood grain, dual zone climate) Fog lights, TT paint, 20"s stock, and the dual exhaust like on the Big Horn. I'm sure there's more but nothing that ever made me wish that I'd spent another $5k for one.
