UL's View Of Aluminum Electrical Components
I have mentioned this clearly several times in several threads, now I will scream it. NO MATTER WHAT BRAND OF RV YOU HAVE YOU MUST MUST MUST MUST REMOVE THE COVER OFF OF THE ALTERNATING SHORE...

While checking and tightening the bus bar connections periodically is a decent idea, the quoted text doesn't in any way suggest that the UL or device manufacturers require this. The only thing I see related to that in the information you posted has to do with checking connections to aluminum wire at devices rated for both aluminum and copper wire as per the maker's instructions. So far as I'm aware, such instructions only apply when using aluminum wire, and not with copper wire.
Tin coated aluminum neutral bus bars are well nigh universal in electrical panels, and there is no requirement that they be periodically checked for tightness with copper wire. In RVs, this comes up more because of the vibration of the vehicle than because of the material of the bus bar interacting with the wire. The same work would be needed with copper bus bars of a similar mechanical configuration.
Again, I'm not disagreeing with the good advice, just that the quote is related.
