Black tank question

Can anyone tell me which manufactures are dumping shower water into black tank. I know some are doing this but it seems to be a big secret. I am getting a new tt in the 24 ft range and would like to avoid this set up.

I have never heard of a shower draining to the black tank, I am aware of several models where the outside kitchen sink drains to the black.

I too would be interested to know if there are any mfg who plumb the shower to the black tank. That would immediately be off the List.

Thanks, I guess what I am asking for is responces from folks who have bought a tt and found out after a few showers that there black was full. I have tt that does that so we never use our shower but some of the places we go do not have showers or at least one I want to us, so the new purchase would be for one that is not plumbed this way. I ask every dealer I go to and they all say never heard of one plumbed like that, it shouldn't be like that, mind don't, ect. I have yet to get one to take a bucket of water out and prove it. So I ask on here for some consumer input. Thanks for the reply.

Depends on individual usage. I had a TT that drained bathroom sink into the black. I replumbed it so it went into the grey. The Black filling up is pretty much my limit of a stay when boondocking.

Since it is fairly easy to dump the grey tank on the go with just a bucket, I fully agree with you. I would NEVER attempt to dump the black tank into a bucket LOL.
