"Not having side windows on both sides of the overhang and being replaced by a large inside mirror would be a deal breaker for us. "
I don't understand this. You typically have windows on both sides. You may or may not have a Front Window.
Having side windows on both sides of the overhang and being replaced by a large inside mirror has me puzzled. I am sure it can be done, but not sure it is common.
Typically, the TC will have small windows on each side of the overhang (cabover). It may or may not have a large window (or two) in the front of the overhang (cabover). This window looks out over the hood of the truck, and is the frequent cause of water leaks.
I prefer no window with no leaks. I sleep in be and get up to take in the view. You can look out of the small side windows, and I typically leave then open a bit for cross air ventilation.
