I'm an avid camper here in Georgia. I currently have a 2004 Chevy Suburban 2500 with 8.1L V8 that tows like a champ. I got a good deal on it when gas was $4 per gallon. I also have a 2000 GMC Sierra 3500 with 5.7L V8. Great truck, but the Suburban pulls much better and handles a lot better on the interstate (no movement from passing trucks). So far, I've loved my GM trucks, but of course have issues and hope to get some answers here.
