I'm the person behind HitchMath. I build the calculators, pull every towing and payload figure from the manufacturer's own towing guide or spec page, and write down where each number came from.
I don't sell trucks, trailers or hitches, and no manufacturer pays for a listing here. When a carmaker publishes a figure that disagrees with another of its own documents, I say so on the page and show both.
If you spot a number that doesn't match your door-jamb sticker or owner's manual, email hello@hitchmath.com with the year, trim and the number you see. I check every report.
