- Cubic yards: 630.0 × 0.500 ÷ 27 = 11.67 yd³.
- Tons: × about 1.4 tons per yard = 16.3 tons.

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
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.
Ordering and delivery
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. Gravel is a broad label, so confirm whether the yard means crushed or rounded stone and whether it carries fines. Round up by about 10 percent for compaction and uneven ground.
