I am assuming that you have a pretty big boat. I have a 3500 # rig myself. I pulled it with a few different trucks, all of which were 4X4 Chevys. The thing I'd say is get a 2500 for the weight handling and bigger brakes. If you can find one get a diesel, you won't believe the power difference, not to mention the improved mileage. Right now I am using a Duramax that gets 20 mph empty, 17 with the boat, and 10-11 with the 13000# fifth wheel camper.
