Thanks for the real-world towing info Mike. It is good to see Mercedes is still going at it after a half-century of dedication to passenger diesels. I've an '87 Mercedes turbo diesel with 300K+ miles that literally still runs as strong as when it was new.
The Benz 3.0L CRD is probably one of the most advanced diesels on the market and, from your numbers, it seems to payoff out on the road. Common rail injector system, 375lb torque, piezo injectors, computer controlled intake swirl, variable pitch turbo for lowend boost, plus low noise and low emissions.
