Yes, there is a second head. Because the head is so small we only urinate into the frwd head. The aft head has a 15gal tank and is used for the other purposes. However, the aft head is my wifes personal space. If your married, you understand!!!! It would just be nice to have a larger tank since I must replace it anyway.
I use the bucket idea when single-handing.
