I am wondering if the weights are different body styles and if diesel or gas ???
Chevy does the same thing...many different weights just depends on the configuration.!!
My personal vote would be go for a 1 ton dually. I prefer a long box so there are no problems or issues with regards to the trailer hitting the cab. The rest are personal choices as to cab, 4x4 or not auto, standard...etc....
Hope you find what your looking for...!!
