Additional freshwater tank/composting toilet

We are in the final stages of shedding the excess baggage, and prepping the house to sell. After years of research and getting our minds right, the fulltime dream should be realized in (hopefully) a few short months. We seem to be set on a 28'-30' AS, late model, not yet purchased.

Under current consideration: My wife came up with the idea that if we installed a composting toilet, and replaced the blackwater tank with a new one to be used for additional freshwater, that our stays in campgrounds without sewer hookups and the occasional boondocking experience could be made a little easier.

I like the idea, but I don't have enough experience to know what the true pros and cons could be.

She has spoken with an rv customizing company who liked the idea and are willing to do the conversion and pipe up the supplemental freshwater tank.

Any input as to why this would be a good/bad idea?

Thanks in advance.

I've thought about the same thing from time to time, but having never used a composting toilet, not sure if I want to. You might consider swapping out the toilet first, go a while and be sure you're happy using it prior to doing the work on the tanks. That way, if you find you don't like it, just swap the old toilet back in and you're done.

Unless you're doing lengthy boondocking (more than a week at a time) I don't see the need. I empty the tank once a week and it is rarely more than half full (2 people; assuming the monitor is accurate). A cheaper solution might be to get a bladder for the back of the truck, fill it (in addition to the water tank) when you know you're going to boondock, a week should be no problem. Search for aquatank2 on amazon as an example.

If you like the composting toilet, by all means go for it. For our part, it doesn't appeal to me and, as is, our black tank lasts for two weeks so we've never had an issue.

As far as having a bigger fresh water tank is concerned, please see this link for how we solved that particular problem:

http://www.amazon.com/Reliance-Rhino...ords=water+can

It's a whole lot cheaper than your approach. Plus, it's basically "infinite." We use about 10 gallons per day so we have two of these cans and just fill them up at a convenient spigot. Unless you are way, way out in the desert, chances are you'll find a handy spigot somewhere nearby.

We thought about going the composting route but have found that we can go up to 2 weeks before filling the black tank. The gray tank is the one that fills up faster. Fresh water can be carried in the tank and replenished from 5 gallon containers. We carry 4 of those containers and find it quite easy to keep the fresh water tank full.

So, if it were me, I would look to change the black to gray.

I was curious if the composting toilets would be more convenient

I know people who do certain types of camping, in certain areas, swear by them. As for me, from time to time, I bring a porta potti. I can dump it in any toilet, and it increases my black waste capacity. I have on occasion, set up the porta potti outdoors. ( and used it for van camping )

As far as an extra fresh water tank ???. I would want to keep the option of being able to go back to the conventional rv toilet. I bought four plastic 6 gallon gerry cans, for when I need to boondock for extended stays. I can also use them to make a water run in the tow vehicle without moving the trailer.
One drawback of another fresh water tank would be towing with the added weight in the trailer. When I use them , I position the full gerry cans in the middle of tow vehicle .

Both of your ideas are very cool though. You could also supplement your ideas with my methods and maybe be able to camp out for a few weeks. ( unless you let my daughters use your shower, which would limit you to a few hours )

Thanks for the input. To me, the appeal of the extra integral tank is not having to lift heavy jugs of water, but certainly the cost would have to be a consideration. Can anyone tell me if the jugs that were suggested impart any off flavors to the water if they are left in the TV in warm climates for a week or two?

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've never left fresh water in the jerry-cans for more than a few hours but it is made of essentially the same material as the built in tank so I would think that it would not make any difference where you kept your water. Believe me, you will never leave fresh water in those cans for very long as you will be using it up. Figure about 5 gallons of fresh water per person per day assuming you don't use campground showers & toilets.

I carry store bought gallon jugs of water for drinking, or water from home.

The convenience you lose by having to lift containers of water…you gain by being able to restock water without moving the trailer. My friend uses an rv water pump to load water into the camper from containers.

I believe that the 28' and 30' have different fresh water capacities. 39 Gal versus 54. We are going to add the composting toilet to increase our dry camping capabilities - gray water/black water. Also carrying 8 jerry-cans of water in the back of the truck (don't forget to account for the weight).

Depending on where one intends to park, dumping gray water is probably against the rules.

Carrying more fresh water is not really helpful if one can't get rid of when it turns colors.

Our gray fills first, so when parked with no connections we try to remember to pour all the gray water we can in the back tank.

Do dishes in a pan and empty in the toilet, etc.

This extends things as much a anything, and no hardware changes.


Regards,

JD

Check out "Gone with the Wynn's" addition of composting toilet and clever black to gray tank conversion. Many feel more gray is best.

I've been fulltiming in my '58 and installed a Nature's Head Composting Toilets: Saving Our Water for Tomorrow composting toilet june 1. It's awsome! there is no smell from it- it has a small fan that draws .02amp/hr and pulls the interior air through the toilet and out to a vent you would install. i'm by myself and was sceptical but i have no tanks and needed to go this route. it works great. #1 gets diverted into a big jug that i empty every 3-4 days into a regular toilet and #2 goes into the bin in the base. so installed june1 and did not have to empty it until end of sept. everything is easy to empty into a regular trash bag and was totally composted, smelled like dirt. i gave it to a friend to fertilize their rose garden. more people more frequent emptying of course, but i'm told 2 people might need to empty it every 1-2mos.

i like it too because it's a full size thing and not uncomfortable to use.

i recommend it,

Not mentioned above is the consideration of how much extra weight you will be adding with an additional full freshwater tank.

We have a 27 ft with 39 gallon freshwater tank and a GVWR of 7500lbs.

39 gallons of water weights 328.77lbs. If you have a 59 gallon tank that's 492.06lbs.

In my case that would be 656lbs added to the Airstream and taken away from my Airstream's payload. Our last CAT scale readings showed our Airstream presently weighted in at 6893lbs.

Keep in mind, we are full timers. That would really be pushing it in the weight department. Also, the fresh tanks are placed directly over the axles for perfect balance. You would be offsetting the balance of the Airstream with an additional fresh tank.

Up above AnnArborBob mentioned the Reliance Rhino water jugs. They're excellent. We have 4 of them.

We haven't had hookups since June. We are always dry camping and boondocking. Family of 4. Our black tank usually lasts for 18 days, and could go further if Dad here went #1 outside.

Our fresh water, if we don't take showers but twice will last us the same two weeks, usually I'll end up toping it off with the Rhino's.

We have considered a compositing toilet to eliminate the need to dump. But one of the things you have to do with that is empty the liquids regularly. And depending where you are camping, say dry camping in a National Park, you might no have anywhere to dump out you pee. Although I'm sure they would be a pit toilet. But it's worth thinking about.

I've been using them for about 8 months now. No issues with flavor. they are BPA free.

The jugs are 5.5 gallons and weight 45lbs each full. That's about the weight of a bag of sand.

A friend of ours bought a small 12v pump and he just lines the jugs up and fills the Airstream with the pump.
