As an aside -- for those with less demanding towing requirements than the OP -- Chevy is releasing a new Duramax diesel-powered Colorado (their smallest pickup). It has a 2.8L 4-cylinder with roughly 180 hp and 369 ft/lb of torque. The 4WD version is rated to tow 7600 lbs and, while it hasn't received an official EPA mileage rating yet, there is a good chance it will exceed 30 mpg on the highway (unladen). The 4-cylinders in a sinlge cylinder bank should help to keep maintenance costs down, as well as the 7500 mile oil change interval. It might be an attractive option for anyone with the 18-22 foot Whalers, that also needs a reasonably economical daily driver.
