my boat is still covered, but in th front were the toliet was, they had made a dorr that hides it, you lift up fold back.
After I removed the toliet I use to keep the tackle box there, out of site out of the minds of the croocks!!
Not sure how big it is there, but its like 15X15X15 cube, I figure thats might be 5 gal or better??
So I figure that I can put a water tank there, use the thgur hull for the water pick up, put a Y vaule and chose if I want salt Or freash just turning the leaver.
Like this, all would be covered under the door, I will have to take pic's when I uncover the boat to give you a better Idea
