Hmm, they might be easier to pull on rough ground than a wheelbarrow is, to push.
A landscape guy helped clean up my yard, and I offered him wheelbarrow to use (I'm proud of it's front wheel, which is a huge green plastic ball).
He rejected it as "too slow". he had a big plastic "Brute" trash can that he could pick up or drag faster than he could push a wheelbarrow. I wish I were still that strong!
I think that "30 gallons" is around the same as "4 cubic feet", so he 3wasn't giving up anything in size.
