I am towing a 2720SL. Important difference between my situation and yours: I not only have the 6 to 8% grades (or more) but I also am encountering them at fairly high altitudes (often well above 10,000 feet). A normally aspirated engine (i.e. one that doesn't have a supercharger/turbocharger) only has about 50% of its rated horsepower at those elevations because of the thinness of the the atmosphere. So I'm going to have to start with about twice as much rated power to still have bearable performance as you would.

Ray,
You might want to consider the Gear Vendors Under/Overdrive as an answer to the power problem.
