I have the Cummins and I see according to the owners manual there is no break-in period (glad I don't have a gasoline engine, 300 miles at 50-55 would be hard to do), so my question is more with the towing. One section says no break-in for the cummings but the other says no towing for 500 miles due to the drive train. Then it says when towing a trailer for 500 miles do not drive over 50 MPH. 50 MPH is the minimum speed on the turnpikes around me. I will be pulling a Grand Design Reflection 5th wheel. How important is this 500 miles "break-in while towing"
