Carport pad tips
Most steel carports can anchor into a compacted gravel pad with auger or rebar anchors. Make the pad slightly larger than the frame and keep it level so the frame goes up square.

How deep
Four inches works on firm ground for cars. Six inches is safer for trucks, heavy SUVs or soft soil.
Buying the stone
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. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
Tools for the job
For anything bigger than a small path, rent a plate compactor; hand tampers cannot match it. A wheelbarrow, shovels, a hard rake and stakes with string are the rest of the kit. Wet the stone lightly before compacting so it binds.
Common mistakes
People often forget that compaction reduces volume, so they come up short. Others order clean, round stone where a packable crushed stone with fines would have stayed put. Finally, dumping the whole load in one pile far from the work area adds hours of wheelbarrow trips.
