Looks like a spoke too soon as the Dodge (CDN) website has now been updated back to showing the $2,000 consumer cash and 3.0 % interest rate.
One thing I just remembered, I asked my dealer to provide me with the factory build sheet of my vehicle. When I recieved it, I noticed that, even though I did not select the trailer option, my vehicle was built with a engine oil cooler. So I guess the $200 option is just for the wiring harness.
