Max Zero Fuel Weight (MZFW) for my 1980 Piper Dakota

[egec]

When doing my W&B, Foreflight asks me for this number.

My POH / AFM doesn't reference MZFW anywhere.

My Max Gross Weight is 3,000lbs and my fuel capacity is 77 gallons, 72 usable.

Should I assume I don't have a Max Zero Fuel Weight?

If so, what number would I use? 3,000? (which would basically mean that I'm unrestricted up to my Max Gross Weight)

Thanks!
