I know I'm really late getting in on this post so I don't really expect an answer. I found this by searching info on macerators.
I have one that came with my '14 Bounder and detest it. As mentioned previously, it is noisy and the neighbors all know what you're doing.
After a particularly disastrous trip lately, the last straw was when the macerator decided to die a horrible, groaning death.
The unit is in the shop for a myriad of things and one thing they are going to check on is if I can use it without the macerator. It has two toilets so I thought it may be necessary because of that. Any thoughts and opinions?
It WOULD have been a deal breaker for me, i.e. I wouldn't have bought the unit if I'd known it was on there. Lesson I learned: if possible, camp a night in it first before finalizing everything.
