The reason that the salesman told us they would have to build the truck is that we want the SuperCab, not the SuperCrewCab. People who get the SuperCab are usually trying to save money, so they don't get the expensive packages.
We added the packages to get front seat console (it has been DECADES since DW sat in the middle of the bench seat), rear camera with trailer assist, reverse sensors, cab step, blind spot system, pro trailer assist, max tow package, moving pedals, and tailgate step.
The only thing I wanted and can't get was the extending tow mirrors. They are not compatible with BLIS, and I wanted BLIS more.
AND, it's silver to match the Airstream!
