We went to a dealer in VA today and looked at both the Keystone Fuzion and the Heartland Cyclone. We checked out the web to see what people say about each. We found some very negative articles about Keystone. Someone stated that Keystone is such a big company that you are going to have a few unhappy owners who are going to speak out. We did not find any negative comments about Heartland. I'd like to know what other Heartland owners think about the customer support they get from Heartland and if you are happy with your purchase. Also, if anyone has the 3712CK, how do you like it?
