if there isnt any distinguishing features on your RV, then its just another rv similar to all the rest on the market... and as it sets there, priced at you would LIKE to get for it, its just getting older, more weathered and less valuable every day... so a lower price may be the only incentive to help it sell, as it can be the "distinguishing feature" that allows your trailer to beat out all the competition.....
there are many "distinguishing features" that can hinder a sale as well... such as most shoddy/poor quality/ugly DIY work done to it, and so even if the rv is equipped with what may be a desirable feature, if its ugly or installed shoddy, it will hurt the sales price...
there are far too many people who put a high price on what they want to sell, and still end up taking a much lower price after all the time and stress of waiting and trying to maximize their sale price...
BUT, just like YOU, everyone else likes fair and affordable prices too, so when one decides its time to let the item go, price it right, price it to SELL, and move on to what you want next..... especially in a flooded market.
