Yes, US "cowboy" types tend to buy trucks big enough to haul a gooseneck and brakes on truck enough to stop the rig if trailer brakes fail.
Generally heavier trucks have larger compoments that last longer. yes the cummins adds some weight to front, but then again it s a 1,000,000 mi motor. the mopar truck will be in scrap pile long before the cummins need a rebuild.
car salesmen? don't even get me started.
