I've been in the construction industry for over 40 years and I can count on one hand the number of differential failures any of my subs have had during the life of their trucks. I'd say about the same average as the babied ones.
I'm not suggesting that you go against the manufacturers recommendations, just stating facts.
Around town may provide the same, or greater based on driver, initial torque but the sustained torque thru the diff is greater on a long heavy haul. Most contractors don't run for hundreds of miles at a time.
