- Cubic yards: 600.0 × 0.500 ÷ 27 = 11.11 yd³.
- Tons: × about 1.4 tons per yard = 15.6 tons.

How thick to build it
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
A 12-foot width gives tight but workable 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.
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. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
