Yes, price it right. If you're looking at NADA pricing, use it correctly. A lot of people find their RV, the year, the model, etc and then get the options list. Please note the following at the top of the options list.
Option note: Only select options below that are in addition to standard equipment and equipment noted in the manufacturer or year notes show above. If you are uncertain of what came standard, please contact your manufacturer with your VIN.
If you don't have a listing of what was standard equipment, find one on the internet or call the mfg. I've called on several for sale adds where the pricing was way too high and then talk to the sellers to see how they came up with their pricing. Most of the went to the NADA listing, then the options and then started checking off all of the features their RV had - not the options. They'd check the TV antenna, the standard sized AC, the standard refrigerator, the batteries the bathroom sky-light, etc, etc, etc.
Then you get them to go back to the NADA site and read the above note and you can just hear the dollar signs melting away from what they thought their RV was worth. When they fix the options, their RV is worth many thousands of dollars less than they thought it was.
Some of them will fix their asking price and others have already planned on spending the inflated price and don't want to hear anything about it. Those are the units that sit there forever.
