One site, that may have feedback from customers:
RV Service ReviewsTrying your best to feel out, how they work with customers after the sale, education (PDI), warranty wrok, fixing issues up front, etc.....
Inquire about service times on warranty work, turn-around times,
Sometimes hanging out at a dealer, you will get a vibe from the service center & customer satisfaction.
When shopping are they ONLY worried with selling(telling you what-ever, pushy with sales tactics), not matching you to the correct unit & have a way to help with product satsfaction.
Visual, does it look organized, customers scheduled, accessible, etc...
Repeat customers.
Search on this forum, some CW locations, get repeat threads on their service.
Good Luck
