David Kopelman sells clothes out of an igloo. Actually, it is a renovated pull-behind Avion trailer decorated for winter. In spring, the trailer exterior will be transformed into a mural of iconic Asheville architecture. But inside is Northville Clothing. Where every square inch counts, the walls are lined with urban outerwear purchased at a discount for resale. The trailer is parked on a gravel lot in the River Arts District, with the permission of property owners Hedy Fishcher and Randy Shull. But one of the reasons Kopelman opted to sell out of a trailer is mobility; he wants to sell at festivals. His love of interacting with people made it impossible for him to operate exclusively online. The concept of mobile retailing is a growing trend that lags the food truck trend in regulation. Of thousands of mobile retailers now working in the United States, at least two, Hazel Twenty and Northville, are open for business in Asheville. Kopelman currently operates with a temporary use permit, valid for six months, while he works with the city to draft an ordinance peculiar to his cause. While mobile retail shops usually have lower startup costs than food trucks, it generally takes them longer to become profitable. Rolling microbusinesses, like Kopelman’s, can be a step-stone for entrepreneurs, because starting small can put them in a better position to source capital for bricks-and-mortar establishments.
