The NADA is probably a current value. I would think that the actual price when new would vary somewhat with different dealers. Perhaps Jayco could provide a suggested manufacturer's list price, but they might not have that figure in their files. I wonder why the insurance agent is insisting on a price when new - they don't usually need that when insuring a car - just the current replacement value. So why not the same for a trailer ? When we added our 5er to our State Farm policy, they insured it based on current, not new, value, and what it would likely cost to replace it with a similar make, model, and year.
