The rear of a trailer has the most bounce. The only damage I had was when my wonderful dealer abused the trailer and bounced it so hard that the pantry shelves broke down.
The rear kitchen is fine for us because we travel and don't sit in it and look out. The kitchen takes up less that two feet of space, except for the refrigerator is in the slide. I would rather have it just inside the door and vented thru the roof. Venting out the side of a slide requires a fan which wastes battery power when dry camping.
