I'm looking to add an "parking pad" for my RV and misc trailers next to my driveway and house. So far I have cleared the trees and am in process of clearing an basketball hoop. The size would be about 9'X60' (540sqft). The ground is level.

I was planning on just digging about 6" down and putting in gravel, but after a little bit of research, gravel could be a ton of work. Apparently, I need to layer it? I'm not exactly sure how much I'm saving using gravel over asphalt or concrete. Everything else at my house is concrete, so I would prefer to avoid asphalt.

Has anyone else built a low cost parking pad before that can offer suggestions?
