I flew across the country and purchased my motorhome from a CW in Georgia simply because they had a great price, and I would gladly recommend the retail store for last minute overpriced RV supplies/products/components/appliances that you must have immediately.
However, I would never take my motorhome to any CW for any type of service or installation. Just far too many negative reviews from too many people from every single location across the nation.
Check out Yelp reviews for the location you intend to visit. That should give you an indication of the location.
I did not use them, but I did get an estimate to install a Winegard satellite system. Then I had a local high quality rv repair outfit which advertised that they would match any competitor's price do the work.
The Camping World price was very good to me. Although they still grumble about it, the rv repair outfit gets my continuing business.
Thanks for all your posts and I will continue to read them.
Any CW is at least 100 miles one way from my house. Travel costs and time have to be considered also. I have s couple of quality shops nearby and will use one of them. That may be better also if I need any adjustments or repair work on the system later.
Being in business for many years I learned that cost is not the primary reason to select a product or service, quality and convenience is more important in the long run.
