tow.

Most towing calculators answer the wrong question. They check your trailer against the tow rating and stop there, when the limit you hit first is almost always payload. These check everything at once and tell you which one binds.

Three limits. One complete picture.

Three things this site does differently

01 Payload is checked first

Passengers and gear come out of the same number the trailer tongue does. A half-ton truck usually runs out of payload thousands of pounds before it runs out of tow rating.

02 Every figure names its source

Regulations are quoted with their section and linked. Where a number is manufacturer guidance rather than law, the page says so instead of dressing it up as a rule.

03 Canada is not an afterthought

Results come in pounds and kilograms together, because the compliance label carries both. Reference pages are written by province as well as by state.
