I always recommend that when purchasing, check the NADA price because NADA always prices these fiberglass RVs low and use this figure when buying. You can adjust your offer down based on the condition, etc and work your way up if the offer is not accepted. Print out the NADA report and have it with you to show the seller.
think the reason NADA is low is because the bulk of Scamp
sales are private therefor NADA does not have data to base their price on.

I recommend exactly the opposite to the seller. The seller should always say NADA don't have the actual facts on what Scamps sell for.
