Porta Pottie

Hey Folks,

I am deep into the bowels of my rear end separation repair. I've started pondering the advantages of doing away with the black tank entirely and going with either a composting toilet or a very high end porta Pottie Thetfords curve comes to mind. We use a porta on our boat which requires dumping every summer. We use it for all facets of the job..,

My thoughts are two fold. 1 no tank, no stinky slinky I can dump the cassette virtually anywhere there is a toilet. 2 with either a porta or a composter I still have the dumping so why not save quite a bit of cash and go with a porta .

As always your thoughts would be appreciated.

Lucky Dave

Won't you still need a slinky for your gray tank?

Or is your Airstream old enough to not have separate gray and black tanks? In which case, if you get rid of the black tank, where does your shower and sink water go when you replace your only tank with a cassette toilet?

72s did not have gray tanks. We have a Porto potty in our Avion and it has never been a problem as long as you have access to a dump station or restrooms. Gray water has to be dumped properly anyway. When we get rid of the gray water, we dump the Porto at the same time. If we have sewer at the site, we dump the Porto down the on site hole, the gray water goes there anywhere. Our Porto holds 5 gallons. Jim

I applaud those who can live with a Porta. many years ago I had a boat with one and I got tired of having to cart the thing to a toilet. We also got tired of the perfumed smell in the boat from the chemical used to disinfect and mask the fecal odor. I did some extensive work to install a bladder holding tank, pumpout, and real marine toilet. I would never go back to a Porta.

We have camped with both over the years. You don't mind hauling a porta to the dump station when you're younger but it gets to be a real drag as time goes on. The cassette is easier but you're still carrying five or so gallons to wherever you're going to dump. Maybe a small two wheeled cart of some type. My personal choice at age 69 is the permanent install but as with most amenities it depends on how much aggravation you are willing to put up with. Different strokes for different folks.

Go Porta

I would go with the porta potty the ability to dump at any restroom and not have to wait in line or get out the rubber gloves is a huge plus. If I were to do it again that is what I would do for sure.

We used a portapotti in our 54 and it worked out well. With a permanent tank we apply the same principal by dumping into a 5 gallon blue tank every two days that can be carried to a restroom or porta john when camped where there is no dump station.
If the tank weight is a problem just empty it more often.

Our our 54 FC we're going with a Natures Head composter. Benefits over porta-potti are they separate the liquid from the solids. The liquids can be then taken separately to be desposed of, and the solids are composted down in the toilet for easy disposal.
I plan on having the liquids drain into our 'grey tank' which is vented, so will only have to dump the solids once every couple months or so.

We ditched our black tank use a Porta potti. Works great. We use a blue boy for our grey water and it works good for us as well. Most sites don't have full sewage hook ups so its either hook up the trailer, go dump , then return to the site. Whata pain! Not to mention no Black tank means less junk in the trunk ,less weight, less chance of floor rot around the toilet flange.
We use the Thetford 550e. Nice unit! We can get three days until dumping it. Two if its a beer night.

As with so many things RV-related, much depends on your use case.

We travel as a family of 5 and often stay in state parks where the public toilet facilities are substandard (distance/cleanliness). Hence the toilet in the trailer serves all needs. A porta-potty would fill up quickly. We have to stop at dump stations to dump greywater, anyway, so having to dump a porta-potty as well would just be an extra step. The few times I've used them I've found them to be difficult to keep clean and sealed.

I know that the b-van crowd swears by porta-potties. For some camping styles I can see how they would work well.

But I'm ever so glad that my Airstream Interstate B-van has a wet bath and black tank instead. Especially since it has also got a macerator pump so I don't have to mess about with a slinky.

I installed a Thetford Curve in our 66 Tradewind and it works well for us. The black tank now acts as the gray tank for sink and shower water. See Dan's 66 Tradewind Improvements (post 23-30) for details.

We only pea in it. We can go 5 days normally. It is cheap, lightweight, easy and clean. Whats not to like?

Thanks all for your repkies! Here is what I will do: Fix and reainstall the Galvanized pan for the black tank. Install the plumbing, basically have it ready to go should I ever decide I need a black tank. I looked hard at composters and they are very nice but out of budget. The Thetford Curve on the other fits nicely into my budget and I can spend the money elsewhere. Thank you all!

Fyi.There's a hold down plate for the Thetford Curve so it stays in place during transit.
