Center split bath - black tank
We are renovating our 1969 25’ Tradewind. We’ve had her for a few years now, and only recently have we found more time for the reno. As you can see by the attached picture, we built gantries and did a shell off. We are almost done reinforcing the frame and painting it with POR15. Our plan is to full time for a year starting this summer, so we’ve got our work cut out for us.
I’ve searched the forums and have read so much, but I feel like I can’t find the exact answer. We are moving our bath from the rear to a center, split bath. We are planning to add a grey tank in the frame in the area of the axles, and a black tank above deck with a low profile toilet (to keep from freezing if we venture into those temperatures). My questions are:
1) I am looking for the actual black tank that I can use above deck in a center bath. Has anyone done this setup that could recommend a specific tank?
2) I’ve read that the grey tank should flush through the black tank. How can this be achieved with my desired plan?
