Vagabond 47 - holding tank location

[klrochette]

Hello. We are considering purchasing a Vagabond 47. The previous owners replaced the forward head with a composting toilet and it's our understanding the holding tank was removed. We are trying to learn where the holding tanks are/were installed. Can any owners/previous owners shed some light on this. We are considering reinstalling the holding tank but are trying to determine the extent of such a project.

Thanks!
