FWIW, looks like an LT since it has leather. It should also have the 5.3 since I don't think you could even get the little motor with a 4x4. Does it have receiver hitch under the bumper? Can't tell if it's got the tow package without a nice shot of the rear...
A VIN would be nice if you could get it. I don't know anyone offhand but I'll mention it to my old man - he might know somebody looking for such a beast.
