description
A beam model balances every load about the coupler. Bumper-pull trailers should carry 10–15% tongue weight, 5th wheel / gooseneck rigs 20–25% kingpin weight — too little unweights the hitch and can make the rig sway. Always confirm the print weight on a certified scale and keep every axle and the hitch within their ratings.
