Arctic Fox is mainly only popular in the Northwest USA. Dealers have a hard time selling them in the eastern half of the USA as their customers have had lots of problems and quality issues with them.
Not correct that AF/Nash requires their dealers to have their products as their main brand they handle. Huge American RV and Camping World location on the south side of Grand Rapids MI has Lance as their main TC line and for many years, and they also sell Arctic Fox, Travel Lite, and Cirrus TC lines.
Per their salesman own verbal words, Arctic Fox TC's are hard to sell as they do not have a very high reputation for quality in the Midwest and some other areas of the country. Lots of customer/owner complaints. Not my words, his!
