I dont have the same camper but I do have the black tank flush .
Altho it works exceptional make sure no one is line behind you to dump so that you can take your time and get it flushed good after each use .
some have put on a clear elbow so that they can make sure its clean .
i have not yet but will soon ...... since we dont number 2 in our camper i do not have a problem watching flow till clean ...
