To follow up, I misread your posting here…you do state a capacity CF figure, but it’s overstated for what the RF16 provides…
You have a significant error in your stats here for this refrigerator/freezer.
It appears you’re quoting stats for the SunFrost RF16, based on the numbers you provide. But the volume you quote is the SHIPPING volume, not the capacity. The RF16 has 3.91 CF freezer, and 10.4 CF refrigerator space.
