Retail staff rarely ask about maintenance schedule directly, but their questions almost always lead back to it.
Why maintenance schedule matters on the Diamond 4

Practical notes for buyers
Cash flow is the quiet constraint behind maintenance schedule: the cheapest option is rarely the one that frees the most working capital.
Freight consolidation changes the answer to maintenance schedule at container scale, which is why small and large buyers reach different conclusions.
