I stopped by the Lowe's on the way to Chilliwack - saw the same ones you did. Two of them would work for the 19.
I took the dimensions with me and checked them out in the 19 model they had. At the end of the day, decided they were a bit too big, and the stock sink would work just fine. There was a bit of back and forth on it, but we really don't need a deeper sink. We will probably wash most dishes outside like we do now.
Besides, I wound up adding two or three more options once I was there, that I had no intention of adding before I got there. Had to draw the line.
Thanks again though for the recon.
