It's a matter of peak flow. Just the two of you won't be a problem, but a larger tank will allow more settling at times of peak flow and likely pump less often. A small incremental cost for a larger tank once you get the backhoe onsite.
Good benefits if you ever want to expand or sell. The larger tank will extend the life expectancy of your leach-field. Might be worth a couple $100 for a designer to set the best combination of leach-field size/life vs, tank size for your lot size and soil types. In 2027, I wouldn't be surprised if regs are tighter and a better design will be a sales bonus for a few hundred $$ now.
