Depending on the combination of the 5 speed’s low gear ratio and the rear end ratio there may be times when you wish for creeper gear below 1st gear, as MSM suggests below. Also with the 237 engine you may find fully-loaded acceleration to be bit leisurely. However for a farm dump that probably that’s not likely to be an issue.
We’ve operated a pair Macks on the farm for many years. One is a 70’s era “R” model tri-axle with a 20 ft dump box. It’s got a Mack 350 and 15 speed transmission (10 speed + deep reduction). As such there's a gear for every situation. Also on the road it steps out pretty even fully loaded.
