RE Thor sew pipe issue:
I have a 2017 Thor Axis and the indicator lights for the gray and black tanks were wired backwards but the actual pipe plumbing was correct. I knew the plumbing was correct because I have transparent piping and my own macerator so I can see the sewer water as it discharges through the pipes.

We have (had) the same problem on our Tuscany DX. Although we suspected the problem for over one year, we were not able to convince the dealer, until recently, when we were no longer able to empty the gray tank. The problem was verified when sewage backed up into the shower.
The dealer found the backwards connection and fixed it. We submitted the claim to Thor yesterday, and they denied the claim. This is a 2018 coach we have owned for 18 months.

Go to the beginning and read the whole thread. Pay attention to post #4 and #18.

In my 31W the bathroom sink dumps into the black water tank.

That's the normal plumbing route...

Welcome and so sorry for your problem. We had the black tank replaced because where the plumbing goes into the tank had holes in it and thor just use plumbers putty to seal it.

We are seriously considering a 32.2 Miramar, how do you like your unit other than the plumbing issue? We currently have a class C.
