Its basically recommended practice. If one of those rivnuts slips loose and starts to spin while you're loosening or tightning a screw, you're in a bad spot. Some people do swap them for anchor nuts, which are rivetted in place and this is what you'd see more in vans builds as well.

How important is it to epoxy the rivnuts? I see that you pretty much always epoxy rivnuts. I am looking for further knowledge on this.
