I have a Starcraft Starflyer which comes in at approximately 1200 lbs dry. Installed is an air-conditioner, but no heater and the icebox has been removed. Just guessing, loaded, I am under 1600 lb's. Will have to check on a scale. Here is my dilemma. I just got my scale in and measured the tongue weight. I am at 96lb's. I am way to light, would like to be around 160lb's. I have rearranged what I can. What is the best way too add "usefull" tongue weight?
