NADA is based on actual sales and highly unlikely there are many sales in the USA of a 2013 RV much less in your immediate area. RV's can be selling at a hefty discount when people lose their source of income or develop medical or other problems that ends their RV lifestyle.
I would expect that the current owner did not pay cash and has an outstanding loan with a finance company. They are going to want to get enough from the sale to pay off the loan. Not likely that they will be able to do so only one year into the loan but they are going to struggle with taking a big loss. These are sad times for millions of Americans.
