Grand Design has been around for a while - and build good units. They have one of the best reputations in the industry for customer service. They build three lines at this point: Solitude (high-end, full-time type units), Reflection (fifth wheels and travel trailers; lighter than Solitude and called "mid-profile" - but still suitable for extended stay and some of us full-time in them), and Momentum toy haulers. They had some recent issues with the wrong axles being installed by Lippert (the chassis supplier) on one model, but Grand Design builds good quality. Head over to the GD owners forum and read information written by people who actually own them...
