We had tongue weight problems with our Coachmen RKS. Always had to fill or partially fill the fresh water tank under the bed to provide sufficient amount of weight on the tongue. If we loaded too much weight in the kitchen area, sometimes even a full fresh water tank would still not allow enough tongue weight and sway issues would be present. We finally decided that it was just inherently a bad set up and bought a used Hensley Arrow to take care of the sway problem. Other than that, the trailer was our mainstay for camping as the size was just perfect for state and forest compgrounds.
