Two big issues.....empty RV and California roads.
I hate squeaks, rattles and noises and chase them when I hear them. You're going to get MCD shades banging if they're not set right or have foam bumpers. Rattling doors if not closed correctly, entertainment equipment not secured in overhead cabinets etc. I'm sure your coach has rattles and you probably chased many when you first got it.
Unless something is broken or literally falling off the coach, most will disappear when fully loaded and you rectified some of things that move around and make noise in every coach.
