I have never had a pro series camera damaged by abuse. I don't think it's physically possible for a human being to damage one without a lever effect eg. falls with an attached long lens, or foreign matter in the mirror box.

The weakest physical point of high resolutions DSLR, whatever the make, is the alignement of the mount and sensor axis.

Any wall involving a shock on the lens, even a short/light lens, will most probably take the mount out of perfect alignement which will result on images with an unsharp area.

Even if it appears to be still working fine, any camera having sustained a fall must be sent for repair if perfect results are still expected.

Cheers,
Bernard

Well I would agree that the camera should be checked, my D300 has been banged around pretty good and on its last inspection by Nikon had no issues with the lens mount.

Yes. which is why I tend to mount a 50/1.8 quasi pancake lenscap, or a 20 on mine while travelling

Probably a smart approach indeed.

Actually, I would be more worried about internal misaligments (sensor, mirror, focus sensor) from sustained transport vibration; of course in a few years time the sensor will use the VR technology to self-align, and the focus system may well do something similar.
