1988 Excella tank sizes?

[jeepinaldo]

Hi there,

I'm looking to add the seelevel tank monitoring system to my excella for the fresh, black and grey water tanks. Does anyone know how tall the tanks are (and therefore what length sensors I would need)?

I'm planning on replacing the entire bathroom in the trailer as it's super old and grubby, so I'm thinking it will be easier to access the tanks from the top, if I'm taking some of the subfloor up. Is this a smart thing to do?

I'd rather order the parts and have them on hand before I start, in case there is a long back order for parts.

Thanks in advance.
