Shop around. I paid about 60% of retail for mine. Careful of dealers who try and make up the difference with overpriced options and poor dealer prep.
I started out with an Adventurer 86FB in mind. That dealer wanted $3k to install a/c and $5K to install an Onan propane gen set. As we walked he complained about an RV dealer down the road who priced so low it put him and his dad out of business a few years ago. We took notes and drove down the road.
I got a better Arctic Fox with every option I wanted and a few I never even thought of for less than the initial price of the Adventurer. A well spent 2 hour drive.
