I was at the dealer in question yesterday. Xtreme Campers in High Point NC was a long time FWC dealer (but are not currently). They've sold many FWC units over the years and continue to service their FWC installed base. I've personally seen FWC rigs at their shop for service, upgrades, etc. They receive regular supplies of spare parts and components.
Full disclosure, my hard-sided rig was purchased and heavily modified at that shop. My service to-date has been outstanding. Feel free to PM me with other questions.
