A good solution is to run external drains from your sinks to a blue buddy or other similar tank. My dad did that with our truck camper back in the 70's and I did it with my GMC. That will help not fill the black tank as much. Dan Gregg and I also added a second drain to our shower pans which also ran outside the coach via a hose that could run on to the ground where allowed or a blue buddy.

You can also find tanks online that may fit behind the black tank but you need to re route the drain lines and/or add a macerator.

Adding a second one and tying them together with a 3" line may also be possible.

Go to tank-depot.com to see if there is something you can use.
