Excavating A Level Parking Pad On A Hillside

I am creating a parking spot for a new camper that we have coming to the farm. The trailer is nearly 37 feet long, so I'm creating a 20x40 parking pad where it'll be permanently set. There is a lot of slope next to our shed (as there is all over our property), so we have a lot of excavation to do.
