My 213 had plenty of noises, and to my wife's dismay, I cannot ignore any of them except for pots'n pans and other temporary stuff. I think the area above the cab headliner is a culprit, since antenna wire and backup camera wire goes thru there and is only taped in place. In addition I found the metal part of the roof rattling against the cap base, so I sent some drywall screws right thru and got rid of most of it. The big tv's are also very noisy, and easily jump over their 1x1" "holder". I also took it out and made a overcab cabinet. On the test ride to the storage lot, there were no new noises from up there. I also had what turned out to be an extra screw sliding around between the cabinet floor and the area under where the lights are mounted above the sofa. (its a sandwich with a 1" depth. I removed the shelf and found 2 screws and some other stuff. At this price point, I don't think that we can expect silence, but some have too many noises. I think mine was on the moderate side. I'm also dogged about noises and break out the silicone sealer and foam insulation on a moments notice.
Speaking of dogged, what kind of dogs do you have birdbybird? I have 2 Mini Schnauzers.
