You can use the trip plates to transport an unregistered vehicle from point A to point B.
If you're never going to take it anywhere again, does it need to be titled, registered, insured, yada, yada, yada? It may depend. state/county/local laws may apply.
Some jurisdictions have 'junkyard laws' which say that all vehicles on a property MUST be registered.
If you are moving the trailer to a park - does that park have its own rules regarding unregistered or uninsured RVs?
My home park requires proof of insurance at check-in.
