We use an '03 6.0 PSD for towing the 36' Bacardi Silver. It has 10,000 miles on it and everything was going great until our return trip from running the kilo in NC. Then, while passing through Savannah everything just stopped. According to Ford, there were three major problems with the initial 6.0 PSDs. Cold starts, faulty injectors and a turbocharger issue. We ended up with diesel fuel in the crankcase and are still waiting on a final resolution.
