Your automatic has 2 choices it could run in 3rd gear at 2500 or 4th gear at 1725 rpm. At 1725 The Cummins should be capable of making around 175 hp which should be lots of power to tow most 5th wheels down a level road so it surprises me that it chooses to run in 3rd over 4th. I would still trust that the computer know what gear to select. By the time my Ford is pulling hard enough to get the revs up to 2500 rpm I am getting around 5 mpg.
