Depth for an RV pad
RVs put a lot of weight on a few tires and leveling jacks. A 6-inch compacted base suits most firm soils; soft or clay ground often needs 8 inches or more and a woven fabric underneath. Put jack pads or small concrete pads where the jacks land.

Size and access
A 20-foot width gives comfortable room to open slide-outs and walk around the rig. Add a wider entry flare where the pad meets the driveway so you can swing in without cutting across the lawn.
Drainage
Crown the pad or slope it slightly so rain runs off rather than collecting under the rig. Keep the top an inch or two above surrounding grade.
Getting it delivered
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Crusher run mixes stone and stone dust, so it packs nearly solid when compacted in layers. The scale ticket is the real weight; tons per yard here is a planning figure.
