Depth for an RV pad
Plan on at least 6 inches of compacted stone. Heavier motorhomes, wet sites or soft soil call for 8 to 12 inches. Fabric under the stone stops it from pumping into the mud over time.

Size and access
A 14-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
Build the pad a little higher than the yard and slope it gently. Standing water under an RV softens the base and invites rust.
Getting it delivered
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Crusher run mixes stone and stone dust, so it packs nearly solid when compacted in layers. Round up by about 10 percent for compaction and uneven ground.
