figuring grade steepness

I got into a discussion with a guy today about grade stepness. Either I am way off in how grades are figured or he's nuts. He was saying his truck could pull a 30% grade w/o loosing more than 5 mph pulling his trailer (I'd guess around 20,000 lbs when fully loaded). I know he's exceeding legal weight limits so lets not get into that can of worms.

So how do you figure grade steepness?

TIA
Nathan
