Thanks Hornnumb. Looked into the 320. It is skinnier however it is longer as well. We are going to try the Thetford Aqua Magic Style 2. It is slightly less front to back and more round than elongated. I will post once I get it.
Hey everyone, we just purchased our Apex 288bhs. Our last trailer had a porcelain toliet which I loved. So my husband tried to switch out the installed 'Aqua magic V' with a new Dometic 310. Love the toliet however it doesn't quite fit. When screwed in, the back right corner presses against the wall :(. Are there any suggestions to a smaller porcelain toilet than the 310 (19" deep)? And/or are there any 288bhs owners that have found a porcelain toilet or solution that works? Thanks for your help.
