when I do a conversion, a pickup dually axle for the rear is mandatory for truck being used to haul heavy. there's a reason for the additional track width of 4 inches on each side. the bearing offset is moved outwards on the dualy conversion therefore putting a higher preload on the outer hub bearings.
Thanks for making this very good comment. Its not very often that owners even hear of this offset and extra width of the spacing.
