I just go with what is needed to climb the grade and keep the RPM under control and not “lug” the engine.

Thats true, I've found the power band is right in the 1800 area. If I'm running 65 yes its closer to 1500 rpm or so. And if I can run 68 to 70 that's right where she likes to be.
Sometimes that is faster than I want to run with my camper so I'll lock 6th out.
I love the power it makes at just 1800 rpms, its just impressive.
