First, run from that dealer and do not look back.
When we were shopping for Arctic Fox, we started with some used units (both private party and dealer). We were treated very well and wanted to look at new at the only local dealer for AF. We were treated very poorly and started working with out of town dealer 4 hours away. We were not able to come to agreement on price for a new AF with the out of town dealer, ended up getting used one a year later that was just what we wanted, but at a price we could handle.
I have been asked by folks where we bought our trailer, and after some discussion, we find that the local dealer treats everyone poorly. AF is losing business because of this, the others that were treated poorly bought other brands locally at a dealer that treated them nice.
