I have always looked at Camping World like Cabalas and Bass Pro Shops. They may have an occasional good sale but they are not an “RV discount house”. If you need it, they will most likely have it, if you want it cheaper, shop the net.
I have stopped into their stores for things I wanted NOW; however, most of the time I surf the web. Camping World also has the advantage of on-site product installation and RV service. But as usual, service and convenience come at a price.
Some people can change TT break shoes other are reluctant to flip a circuit breaker. The RV market is designed to service all types.
