I faced this problem when Ezell would not supply a replacement tank with different fittings or size. Even when you have the manufacturer you can end up in the same position.
If I was to do it again I think I might go for that composter but room is an issue. Check measurements to see if you can fit one in place.
Designing your own tanks seem to be the only way to get the most out of limited space.
I would suggest designing each side by itself. It is possible to bend the metal to make the tank but that takes more skill than just cutting out 6 odd pieces and welding them together.
Always keep in mind that the company making your tank is not likely to have highly skilled engineers and machinists on staff and if they do they are not likely to build your tank, remember you wanted affordable.
Consider opening the V berth. The projects that cut the whole section out looked like the best to me. Then when the tank fails or you have to work on something you can open the whole thing up just by removing about a 100 bolts, LOL. I still like that set up the best.
I have seen some very complex items made by just cutting cardboard.
By that I mean they took some stiff cardboard and cut it down to fit a side. Then they tape all the sides together, while in place. That became the model. That model was used to create prints and was taken to the machine shop so they could see the product in 3D and have something to compare during construction.
I prefer drawings but think the models are best. I'm pretty sure the last tank I had made was built properly because I gave them a similar tank so they could see what the final product should look like.
I've tried to have stuff built without a model and in one case got back $15G worth of nice looking but not fitting product. Hard to understand with several sheets of autocad prints sitting in their office. Turns out they didn't use the prints, instead they build everything with a little pocket size notebook. When looking at the two pages used in the notebook it was easy to see that they transposed a few numbers and since the notebook was God and the prints never looked at the errors just built on to each other all week, grrr. When someone supplies thousands of dollars worth of prints use them!!! ok ok l know let it go, LOL.
It is much easier to just fit an off the shelf tank and not think of the wasted space.
Have faith that the oceans are going to rise and flood the world, that plague and pestilence brought on by Climate Change is going to punish us for not believing. Please do as they say it is our only hope. :P
