The rule of thumb is that tongue weight should be 10% to 15% of the trailer weight. The stock Dodge hitch in weight carrying mode is rated for 500 lb tongue weight, so that puts you into weight distributing mode (spring bars). I use Moly wheel bearing grease on the ball. Also you want the ball height such that the trailer is level--frame to ground height the same front and rear. Best wishes with your trip.
