Here is a Conventional gravity system which called for a 1250 gallon tank. We ungraded to 1530 gallons, free of charge. We installed 100 Infiltrator chambers in a 12′ by 100′ bed and installed a distribution box with flow equalizers.
Design of system: TBC Septic (from stamped Perc Test)

Customer requested an RV dump port. We also changes from 12″ to 18″ risers on the 1500+ gallon tank.
Risers increased to 18″ to be sure of a flush-to-grade finish.
