I would never disagree that a fullsize turbo diesel is best for towing, but the going-rate on a new one is $35k+. Towing a 3,000 pound boat is well within the limits of what a compact pickup was designed to handle. I used to tow a 3,700 pound boat with my 22R-E. Fast, it wasn't, but it wasn't slow enough to hold up traffic either. My advice is to give your truck a full tune up, hook up the trailer and see how she does. If you'd like a bit more 'umph,' then consider dropping the money on the engine modifications. I wouldn't hesitate to tow that much weight with my V6.
