This is a classic case of figure out your situation because we cannot possibly tell you what the definitive answer is here. Other than you profited once off of the camper being wrecked. In theory you’re double dipping by going for a second round.
Until the actual insurance agents and adjusters show up here, the rest is speculation.
And for those that think a vehicle/toy needs to have a title to be able to or required to (if one wishes to have insurance) have insurance, you may want to refrain from further replies as you’re mistaken.
