Another vehicle? Start with your own numbers
A towing rating
is only one number.
People, water, bikes, the hitch itself. It all comes along—and it doesn’t all count against the same limit.
Understand the calculationThe load moves through the hitch. Tongue weight is part of the trailer’s weight. It also loads the truck.
Read the guideClarity,
line by line.
See what fits, what doesn’t, and what you still need to find out. Each limit gets an honest answer of its own.
Make it your load sheetExample values, not ratings for a particular vehicle. An unchecked limit stays visible.
A few numbers.
A clearer picture.
You don’t need everything to begin.
Start with what you know.

There’s towing capacity.
And then there’s payload.
Where passengers, hitch hardware, and tongue weight meet the door label.

a more complete story.
What axle readings reveal, and why matched weighing conditions matter.
