NADA can be easily manipulated to suit the price you want due to all the options available to click vs the standard options that your camper comes with. For example, you can add fiberglass sides as an option and toilet electric flush to up the value. Plus there is a low to high value. This can range from 12k all the way up to 24k! My bro bought a 2009 830 loaded for 12k which was stored indoors. This was a steal of a deal. He had to drive from so cal to Texas though. There was one in oceanside for 15k he looked at but had alot of rust. About a month ago someone had an 830 for sale for 14k which sold in a couple of days. I think 20k is pretty high as he was first looking at one in New Mexico for this price and it was on craigslist for several months. If you are looking to sell you could probably easily get 18k and 20k if you are in no hurry to sell, but your rig would need to be in perfect condition. Bottom line keep your camper in great condition and get it fully detailed before someone looks at it and you will get top dollar.
