What extras should I insist on in a new Class C

These are not big things but have been important to me:
grab bars on the entrance - big, easy to use and sturdy. I have the fold-in one on the outside and the long vertical bend-out one on the inside. Also a grab bar for the screen door.
Vent covers on the roof.
Tire pressure monitor system.
Power side-view mirrors.
I think all new units come with rear view cameras these days.
