RV values

I have gone to three sites trying to find a value of my Big Horn. Everyone I go to lists all models EXCEPT mine. I have a 2013 3370RK and Kelly, or NADA don't list this particular model. Whats up with this? I even tried looking a year prior and a year later, but no luck

If you know a trusted RV dealer, try there. Their NADA books may differ from the public ones that we have access to.
