We picked up our 2022 Entegra Vision 29S and although the NIRVC new owner training was adequate and I not sure about this one only having one gray dump valve as they noted. We just finished our second trip and used the kitchen sink more this time and Gray Tank 2 is showing about 1/3, even after the gray tank was dumped. Gray Tank 1 went to empty and so the question is....
Is there a hiding secondary gray tank pull valve as our previous ToyHauler had and where is it???

Thanks!!
