MJG

Not familiar with GM much at all. I'm a Ford guy and been through them all. Currently drive a 5.0 SC lowered 3/5 with Corsa Exhaust and its a blast BUT I have always like the early 2000s SS trucks. They were pretty slow in comparison to my previous Lightning and '03 HD but speed isn't my thing anymore. I've find a few low mileage SS trucks I'd be interested in. Two of them are '03. One of them is an '06. I believe the 03s are AWD and the 06 is RWD. Prices range between 18k to 27k and mileage 55k to 78k. Is there anything I need to know about these trucks, any advise to offer?
