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
Measure your rig with slides out and add a few feet. At 20 feet wide, there is room for slides and a path along one side. Leave a turning area at the entry.
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.
Ordering and delivery
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.
