Newer Cheaper SS ????? Help

I was on the lot yesterday, and saw a truck I havn't seen or heard of yet. It was a 1500 LS, but it had 20's and a 6.0L engine. And it is only two wheel drive. It had flashing on the side that said High Output Vortec.

Has anyone else seen this? What is it? Where do I get stats on this truck? Any help would be greatly appreciated.
