We had the same trailer and if I remember right the fresh water tank is 86 gallons and the grey and black are 32.5. each. We had the 4 chairs and free standing dinette. Kind of wish we never sold it. But we have a 2018 Jayfeather now and that is great for us. Hope things work out for you.
2018 Jayco Jayfeather 27 RL, 2002 Ford excursion, v-10, 3:73 gears 4x4 mine. 2008 Suzuki sx-4, hers. Retired Air Force, now Retired.
