What is the best rpm range for highway

I'm building a custom truck and planning on using a 12v cummins engine and was wondering what is the best RPM range for highway travel 55-65. This way I can plan my tire size and gearing to match the engine. From the little reading I've done it seems like 1600-1800rpms is a good range?

For those of you interested its a 1968 millitary Jeep M-715 pickup with a custom shorted utility bed and with be riding on 35-44" tires
