Are you looking for best of breed or just a reliable RV? There are some great ones, but they are mostly in the top tier price wise. For example, Holiday Rambler builds an excellent travel trailer, especial their Presidential line.
Forest River, K-z, Jayco, Sunnybrook, are decent brands and Forest River has models in all price ranges. As the price goes up, you get better construction and materials inside and out, as well as amenities.
