Reality is littered with people who choose to pay too much for too little, particularly those you find in the pacific northwest, where they feel a nice westy is worth 20k plus. If you want to be a part of that reality, then so be it. I gave honest real examples of significantly cheaper vans for sale right now! Not imaginary vans I made up. And while I never mentioned "cruising" NADA it is a well renowned industry standard source for vehicle pricing - meaning unless your dealing with extremely rare hard to find items paying 3x it's recommended price is to put it nicely "silly". I'm giving an educated opinion because someone asked. Of course in the end the real value is up to the purchaser. I back up my opinion with real life examples and industry standard figures. Shoot me your zip I'll find some better priced examples closer to you if you would like.
Bill, your sigs says you're in Ohio. In 2011, Washington State (average) personal income was 20% higher than Ohio State personal income. (That's 13th vs 33rd in the nation.) Just perusing a real estate site, in Columbus (I don't know Ohio, but that's in the center, Ohio's largest city, the state capital, 2009 Business Week "Best Place To Raise A Family" and 2008 Forbes #1 "Up and Coming Tech City" and a name I recognize, so it should be pricey for Ohio), a small but decent house starts at about 1/3 of the equivalent here... around double what my car cost!
So sure, I bet you can get a great used RV for $2K there. I'm in Seattle. Microsoft, Google (yes, them), Amazon, Costco and Boeing all are doing quite well. The market here bears no resemblance to that in Ohio. I know. We looked for about four months.
Beyond all this, NADA has a reputation for being (a) considered less accurate than KBB and Edmunds and (b) regional. Prices are very regional. Partly for the same reason we bought locally... going 800 miles (distances are big on the west coast) to get something significantly lower priced incurs big travel, gas, time and convenience expenses, especially if you are a selective purchaser (meaning you may not want the one you just travelled to see because you hate moisture-induced mildew and that wasn't mentioned.)
I would suggest offering less.Asking for maintenance records.It may be a real creampuff. NADA does not represent accurate real world prices here in SoCal.People are getting a little more for more economical rigs and less for bigger rigs.Good luck.
