Glad this story has a happy ending, your learning experience will continue as you put more miles on your unit. We run 65 mph on flat ground about 99.99% of the time - it's the sweet spot for the Cummins ISL engine (1800 rpm.)
You might find 55 or 60 mph provides a good balance between making miles and fuel economy. We always prefer to be at least 5 mph under the average traffic speed so that vehicles are almost always passing us. Much less stressful.
