I bought the same cap. What did you use under the toilet to get past the flange?

I have been using one spray bottle with plain water to do simple cleaning with after each use. Then I have another bottle of liquid that I found that is used for spraying inside the container. This liquid contains good bacteria that helps with composting. It is probably over kill since the whole process is already happening. I am not at my trailer right now and can't remember the name of product.
Will find out for you.

And I was afraid this was a dumb newbie question...

I have learned a lot from the experience and opinions on this thread. Thanks for all the input. This forum has been a huge help to us!

from what I've read it makes SO much sense, to point of why don't they often now as a factory option. some people are just hung up on the old "poop" thing .. something we don't like to talk about it ! The more you read though, the more you'll open your mind to the idea. I'll be ripping out my old water flush toilet at some point for sure. Just have other priorities expense wise for now ..

check out this video from some full time rv'ers ..

It does make a lot of sense! So much, that I decided to finally pull the trigger today.

Looking forward to reading about your experience. Will you be combining gray and black tanks via that simple external valve so they both hold gray water? Heres hoping it's a serious boon for all that wild camping you do!

We pulled the trigger too. We have Airstream Interstate van and am worried about the install. It won't happen until March because it's in storage. I'm worried we'll have to drill a hole in the side of the van for the vent. And I'm worried about finding the 12v wire. We are not handy AT ALL. Open to all advice! Thanks for all the great ideas on this forum--I know that will help.

Almost there

So grateful for the ideas/advice/experiences in reply to my question. We put a deposit on a consignment 28' unit that is supposed to arrive at our dealer soon. Hopefully, all goes smoothly and we'll be setting sail shortly. It seems the owner passed away and the family is responsible for making the transaction. If we do get the deal done, we'll certainly raise many a toast to the former owner and all the good times he had in his Airstream, while we carry on the good times and traditions for him. Fingers crossed.

The install really is pretty simple and straight forward. Took maybe an 1 hour and a half.

Bumping up an old thread here because we've been boondocking a month this summer and dealing with the black water tank is a huge hassle. It's a 70 mile round trip for us to get to the nearest dump station, which charges $20.

We spend the winter on our 40 ft. sailboat in the tropics. It's an old boat, and after a hideous experience with the 30 gallon stainless holding tank I ripped all the plumbing and valves and marine toilets out of it ( anyone know where I can sell two Baby Blakes?) and we replaced them with two Nature's Heads. We just spent six months on the boat before coming up to the Rockies so we have a lot of experience with them already. My comments so far:

-ignore the advice from people who don't actually have any experience with composting toilets. They don't know what they are talking about and will never admit, nor possibly even realize it. But their comments are worthless to you. The real adamant nay sayers likely have their own little poopie hangups to deal with.
These things wouldn't even be sold in the US if any part of the process was illegal. period. There are many thousands of them out there working just fine.

-we have had better results with coconut coir than with peat moss. It's a different procedure to use the coconut, but the bricks are easy to store. Most importantly, though, is that sometimes you get gnat eggs with loose peat moss. Not an issue for gardeners, but definitely an issue inside.

-the solar vents work great, although they're a bit expensive. We have six of them on the boat for two years now. First thing you replace will be the rechargable battery, but it's a simple job to replace a C cell and you buy a much better one for the replacement.

Now my question:
How do you "combine" the gray and black water tanks? We also have a 27 FB Int'l.

How you combine depends on your trailer and tank configuration. In a 23FB the black tank is significantly higher than the gray, so you can't combine at the drain valve. After looking at various options (pumps, reconfiguring, etc.), we opted to modify our sink and vanity drains so that we could direct them to either the gray tank or the black tank as we choose. In the pictures the valves are the same type ones that you have at the drains (dump gate), and we just open and close as desired to direct the gray water to the appropriate tank. By doing this we are able to use the gray tank normally, but have the black tank as a reserve. It increased our gray water capacity from 30 to 48 gallons, and given that the gray water was usually our limiting factor for boondocking that helps a lot. If we ever chose to return to the original toilet from the Nature's Head (doubtful!) we could still flush into the black tank.

This is very good information bring shared.

We have new tanks underneath with no spin welds yet as they were not sure what the interior layout would be. So no holes in the floor for plumbing yet. If we opted for the Nature's head or other we could save one hole in the floor and seriously increase our gray water capacity.

I gotta say, I'm not totally keen on the composting toilet. My wife is, completely.

The deal she offered me was she would take care of emptying it as needed, if I agreed to keep us in fresh water and empty the gray tanks. Lol. Seems like a great trade off, provided I can't smell the toilet in the meantime. I need more input to be sold on that!
We also use the Rhino 5 gal containers...they do not have ad smell nor flavor to water...we have filled and travel with 4, but found it much easier to fill at our camp site area, assuming there is access. When boondocking outside Borrego Springs, that means a trip to town every 5 days to fill and we dump black in 10-12 days and will fill again. We run gray where we can at our sites and make sure we have biodegradable soaps. In other campgrounds where there is water, we can usually make a couple trips to the water to fill every few days. We also found 20 gal every couple days works fine and takes no time.. We have been happy with this arrangement.
