Inverter Bonding Neutral to Ground

Bonding the inverter neutral would make the RV frame part of the electrical circuit for the inverter

Do Not Bond neutral to ground

I am having a difficult time understanding your logic here. Certainly the inverter (or anything else in the RV) should not bond ground and neutral when operating on external shore power; but when running disconnected, I don't see any potential problem. That does presuppose a proper transfer switching arrangement, either a transfer switch or a plug and socket setup or dedicated inverter only circuits, but that's rather essential anyway so the inverter output and shore power can not fight each other.

Standard practice for built-in RV generators is to bond neutral and chassis ground when operating off of generator power. I know for a fact my Onan is wired that way; the neutral and ground outputs are connected to the same metal bit attached to the chassis. Why should an inverter be different?

(Bonding and grounding are, of course, quite separate safety measures, and serve different purposes. Grounding is used to tie the overall potential of the electrical system to something reasonably close to earth potential, so it doesn't float to a dangerous level. That's far more important in large area distributed electrical systems than in local, self-contained ones. Bonding is done to provide a low-impedance fault current return should there be a short circuit to equipment chassis or whatever, which hopefully trips the breaker or blows the fuse, rather than having the chassis be energized and some unfortunate person form the current return path.)
