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
Measure your rig with slides out and add a few feet. At 12 feet wide, check that slide-outs and the awning clear. 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
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. Round up by about 10 percent for compaction and uneven ground.
