Tha actual cost difference to go to a Dually is around $1,200.
I've used the NADA website a number of times to get dealer invoice and it has always been accurate. I went back and checked just out of curiosity (actually thinking about a 2018 but no pricing yet) and the difference between the dually and srw still comes out $181. Of course, I'm always subject to input errors, but I think I did it right. While the pricing doesn't sound right I do remember there not being much difference to go with a dually when I ordered my current truck, a 2015 Denali. That is with the Denali package and the Duramax as the only option selected.
I also checked Ford and Ram. Ford adds about $1600 and Ram about $1200 for a dually. Go figure.
