I have a 2019 3791RD, same unit with residential fridge.Bkack water is 49 gallons and grey is 88 gallons, 2 @ 44 gallons each. Fresh is 66 gallons which includes 12 for water heater and a couple more for pipes. Probably around 50- 54 gallon tank. I got specs on Keystone website.
Just curious, did you put on a washer/dryer? I'm wondering where the washer drain is plumbed. I've been told it could be any of the three tanks, or straight out the sewer outlet. I figure since yours is the same year as mine it might be the same.
