Both 40 gallon for a total of 80 gallons for the unit. Black tank is an additional 40 gallons too.
FYI, we also ended up getting a twist on valve the same as that mention earlier. None of our grey or black tanks would seal properly (debris in the gate). The dealer did fix them but as an extra precaution gave us the twist on valve with the sliding gate. It took a couple of trips before I realized why my shoes kept getting dumped on each time I took the black cap off, even though I'd emptied the tanks.
Hope you enjoy the rig, we love ours and can hardly wait until the new season gets started for us.
