How thick to build it
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.
Buying the stone
Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. Round up by about 10 percent for compaction and uneven ground.
