Normal people don’t need to haul over 30k lbs on a regular basis. Businesses sometimes do! These vehicles are not supposed to be daily drivers their supposed to be work horses. A 2 ton diesel chassy is made for hauling big loads, and if you don’t need to haul big loads you don’t need one simple as that! Really the only “regular people” I can fathom owning a rig like that are farmers otherwise they really are only useful in construction and other contracting gigs that require lots of equipment hauling to job sites, or in the case of where I work the need to haul multiple vehicles on a gooseneck at a time.
