When you price an RV in NADA, be very careful that you know what options to include in the base price and what options are considered an add-on. It varies with every model. 13.5K BTU AC might be standard on some models, so there would be no add to the NADA price. On others almost every single option is an add on to the NADA base model price. The NADA does not know how the unit was equipped, so the actual value can vary a lot!
On this model, things like a TV antenna, stereo, satellite dish, TV, leveling jacks, cabinet upgrades, outside showers, and some other things, would all be considered upgrades and add-ons to NADA price.
If you aren't sure how to figure the NADA price, go to your local library. They should have the actual book there. Most reference librarians are well versed with the NADA guides. The book will also tell you exactly what you should add and what is included. You can even make photo copies of those pages. If the dealer sees that you have the book numbers in hand, in my experience, they won't even argue the NADA price.
