You should know that not all oils are Ford approved and making modifications to your engine can be of concern if you engine is still under warranty. You pulled one of the hardest pulls in the country with a large load. I wouldn't get to carried away based on that one pull.
You didn't mention your engine, but the diesel is a beast, well suited for towing heavy loads.
