Oh also, two Ac...... that's a tough one. I have a single Ac, and in the heat of the Texas summer without shade, it's warm inside.... but I'm also happy to not have to go 50amp service.
Bob jones rv, mentioned in my pm, can replace the rear fan with a second Ac unit that is operated by extension cord, but they do an ice job of running the cord through the skin. That any you can have two Ac's, but still use a 30 amp pedestal.
Awnings, sure, you can add those anytime, or order it that way. I sort of wish I had them.
A backup cam, eh I dunno, I've been fine without one on the rv and have never thought I really wanted one. I suppose it could be handy, but nothing I'd stress over
