Keystone RV Manufacturing Company does not sell to customers. All of their "factory support" must go through an established Keystone RV dealership, so don't look to the factory to supply anything (parts or missing equipment) without the dealership processing the request. While you can talk to customer service, they will, in almost every instance, refer you to "your dealer for help".....
