Manufacturers from Jinhua (camper vans) and Shangyu (tents) industrial clusters are expanding on Pinduoduo, meeting billion-yuan demand. Chuseniao (Zhejiang Pride Leisure Products), formerly an OEM for brands like Descente and Sam's Club, shifted online after export orders dropped in 2022. Within a year on Pinduoduo, its daily GMV exceeded 150,000 yuan, with 70% of camper purchases for daily use (cargo, strolling) rather than camping. Tanxianzhe, founded in 2004, abandoned OEM in 2008 to focus on its own brand, developing fast-setup tents (3–5 minutes) with UV protection. On Pinduoduo, its annual sales reached nearly 200 million yuan, with 40% of buyers from lower-tier cities.
