Puma 31QBBH Grey Tank Size

I just purchased a 2020 Puma 31QBBH which has two grey tanks with two separate valves and drain points... bummer. The brochure says I have 70 gallons of grey tank storage and one grey tank. As noted above I have two grey tanks and the front tank holds only the kitchen sink water. The back tank holds the bathroom sink/shower and outdoor kitchen sink. I was wondering if anyone knew the individual sizes of each tank. I was impressed with 70 gallons but I fear I have 35 gallons for each. If no one knows the answer I can pour 5 gallon buckets in my drains to determine size...

Yep, that sounds like two 35 gallon grey tanks and I imagine your black tank is 35 gallons also. My 5th wheel is set up the same way.
