Quality wise, GD is right up there with any builder in its price range! What sets GD apart from other manufacturers is their Customer Service! The grease seal issue is a good example, I have read where GD and Lippert have sent out the seals and new brake assemblies to people who were out of warrenty, and then paid for a technician to replace them! I own a GD solitude and I am very Happy with the rig, as well as their Customer Service!
