My Flagstaff 831 RLBSS has a big window in the back and a smaller one in the front.
If you really want a view and openess, you might want to see if FR still offers atrium slideouts on models like they did back when I got my RV. I liked them a lot.
Here is a pic gleaned from the internet, showing an atrium optional slideout. You can see how large the windows are on the atriums. The one my dealer had on the lot at the time didn't have it, and I didn't want to wait and special order it.
