We need more context to know the exact meaning. It could mean that it's a lot of money, or a lot of something else. And it could also mean that it's a long distance.

Haul from hauling?? If that's the case it could mean something like "That was a considerable distance" But we need more data to give a final answer because with just this short statement, we cannot safely assure the meaning, I'm sure there is more information connected to that one.

Quite a haul means “wow you have a lot you are carrying”. The context doesn’t matter. It can refer to many things but it just means you are carry a lot. It’s usually physical and literal but can apply in other contexts as well.
