Question Dometic macerator toilet

[Pam Anderson Borah]

I have new to me a 2016 Newmar Ventana 4311

I have a Dometic 8700 toilet. I need to raise toilet 2 inches. I was thinking of putting a 2 inch thick board cut to toilet base length and width demension What problems will I have with macerator since it is through the wall discharge and not through floor. Recommendations?

I don’t expect you to have any but can you post a picture of the plumbing setup? I am not familiar with the waste line running through a wall. In my experience, I’ve always seen it routed through the floor.
