Wade, the factory cross tube on your truck in NOT intended to be removed. Your truck has the "dealer" installed hitch, where they just bolt up the center section rather than welding it at the factory.
The center section can be removed to install a B&W unit or Torklift SuperHitch.
Here's some links for you to look at BEFORE you remove your factory hitch.
I have the Torklift SuperHitch installed with the Dodge "Factory" hitch on my 03 Dually.
