Conservative estimates for payload + tongue/pin weight. Always verify with your door sticker,
owner’s manual, receiver label, tire load ratings, and ideally a CAT scale weigh-in.
Payload-first

1) Vehicle inputs
Find this on the yellow/white sticker inside the driver door — not the brochure tow rating.
Default 60 lb. Add more for weight-distribution hitch (WDH), racks, etc.
If you enter GCWR, you can also enter estimated vehicle actual weight below.
2) Trailer inputs (choose trailer type)
Typical tongue weight range: 10–15%.
Start with the default unless you have real scale numbers.
Travel trailers and heavier car trailers typically need brakes + controller.
Most “tow rating” setups fail on payload first: people + cargo + hitch + tongue/pin weight.
