Is that 20 tons on Earth or on the moon? There's a big difference, you know...

aren't they talking about mass and not weight? Isn't mass independent of gravity?

Mass is independent of gravity, but pounds (and therefore tons) are a measure of weight, which is not independent of gravity.

On second (or thirdish) thought, this does make sense. It can carry 20 tons regardless of the gravity, but can carry more mass on the moon. Oops.
