Thank you all for the input. It confirms what I had almost decided already, to go for the 19. I originally wanted a 17B, and looked at one, liked it, but the bathroom was really cramped. And my thought of using the front dinette for a permanent bed started to feel cramped too. Then looked at a 19 and liked it even better, roomier all around, and I can get an oven in it, whereas this wouldn't be possible in the 17. Plus some other options and things that are standard in the 19, but would be extra in the 17.
Now for the heart stopping call to ETI! Very exited, it will be hard to wait for it for a whole year.
