With your 5.9 and a manual transmission, start with a good exhaust brake to help in slowing you down on grades. If you find the axle gearing to be off or you need ratios to be closer, address that after the exhaust brake.
Gear Vendors makes nice split for gassers, but their product does not hold up to the deceleration forces a diesel with an EB can create and it will die prematurely. There may be other companies that provide splits for your current 5-speed or maybe you can find a different transmission utilized in a MDT that mates up to your 5.9 that will do a better job.
FYI: I am not a professional Class 8 driver, but I have been driving diesel pickups since 1982..
