RVs definitely are a give and take!

Okay, before you go off on the composting toilet tangent. With a compositing toilet with 4 people you would be emptying the urine container daily.

If you're okay with dealing with containers of urine. You can simply have the guys urinate in a container and then use that for flush water. You just need to make sure there is fluid in the bowl (urine or water) because that's what creates the odor seal between the trailer and the black tank.

Without adding any water you could probably go 5-7 days with the 13.2 gallon tank and 4 people.

I do have portable dump tank which happens to be 13 gallons, I was initially figuring I would have to be sure to dump when the tank was less than half full. Now I guess I don't have to worry about that.

Hey thank you, appreciate the feedback. And since we will probably not be camping for more than 7 days at a time (kids would get bored I'm guessing) I will mark this issue down as solved. Worse case we get a portable black tank to supplement. Thanks!

Here is a crude drawing of a thought I had to extend the black tank in a 19. The idea could even be larger in a 21. It uses readily available plumbing pipe attached to the black tank to extend the liquid storage availability.

Typically the problem in dealing with an RV tank is connecting to it and making a good seal. If one was to use a standard toilet flange they could bolt it to the side of the tank with stainless steel hardware and a gasket. The hole in the flange allows your hand and wrench to get inside the tank to tighten the large washers and nuts. I would get a flange that allowed me to drill my own holes every inch or so around the contact area. Then glue on as much pipe and elbows as you feel will drain. I picture a U shape with a Tee on the end that will have a screw on lid on top so that it can be easily removed to flush the new addition. With down converting at the end and a small hatch you could even design a way to flush from the outside. A win win.

I know a new tank would be the best solution but that is way above how far I want to dig into the trailer.

Let's get real, no one is going to do this.

No way I would take the risk of black tank being stored inside the living area of a trailer.

don't all escapes have the black tank inside?

Yes the black tank in a 21 extends inside your trailer under your pillow.

Yes, every Escape black tank sits on top of the floor, under the toilet and extending into an adjacent interior cabinet. And yes, that's a common practice, especially in trailers that were originally designed to have a low floor (which means most moulded fiberglass trailers).

If Boondocking, I just make use of the natural landscape to pee. That leaves more room for her.

Your profile states " 2014 21' Escape" and you're unaware you sleep on top of the black tank that's right under your bed?

I think most all-molded towables have the black tank inside. AT least the brands that use a marine toilet....
