Hi Folks, 

 

I just joined your group and great info. I'm planning on purchasing a Northstar pop-up in the coming month. At the moment, pretty sure it'll be the 850SC if I end up going with a toilet, or the TC650, if I go sans toilet. 

 

I have no experience with cassette toilets. on here, I've seen older posts and people generally like them, but I've also seen some videos of people who say the stench when emptying is horrific and it's a pain toe get them clean after emptying (multiple rinse outs). I'm  pretty sure I would not bring it in my house (on the carpet) at the end of a trip to empty in my facilities no matter what. 

 

I'm hoping that you all wouldn't mind sharing your experiences - good and bad. Would be a great help in figuring out if it's something I want to get involved with. 

 

Thank you!

 

JD

Stu, if you've never had one, how do you know you wouldn't want one. I can't think of a simpler way way to get rid of toilet waste. No stinky linky coil tubes for me.
I have been a tent camper since my Boy Scout days long, long, ago. Now I need to get up off of the cold ground to get a good nights rest, a truck camper seems to be the best choice. I am here to learn as much as I can.

I prefer to deal with the dump process less often with my 50 gallon black tank. However, there are places with fewer dump sites and a cassette would be more convenient. With my elevated black tank in the slide out, I suppose I could run a hose into a pit toilet...

Greetings britdog!

I have a Northstar with a cassette toilet. Here are some thoughts on it...

 

1.) If I had a big camper on a dually truck with slide-outs and such I would probably have opted for a nice large black-tank. However, with a smaller unit like a pop-up (or my own Arrow-U), a cassette toilet becomes a much more reasonable choice. 

 

2.) The cassette's small self contained size is the winning issue in a smaller Truck Camper unit.

And remember the Thetford Cassette system does NOT require a fresh water supply (other than it's own 4 gallons built-in). It is truly self-contained & independent!

 

3.) A cassette toilet does NOT need a heated environment to function properly. This can be a life-saver when winter hunting or fishing with a pop-up in very cold climates.  :fing32:

 

4.) The removable cassette unit is actually a small version of a typical 'blue-tote' complete with built-in wheels so it can be "toted" to the dump station if you do not wish to break-camp and drive your entire rig to the dump station.

 

5.) You can buy and carry extra cassette tanks if you feel you would need more capacity when you travel.

 

6.) Stinky-slinky hose adapters can easily be made to create a fully closed dump into a dump-station exactly as you would with a regular black-tank camper. I personally do NOT ever 'open-pour' sewage! With hose adapters there is no need to.

NOTE: Tomorrow when I have more time I could post pictures of the adapters and "closed system" I use with my Thetford C400 cassette toliet. Also note that Thetford markets a fine selection of waste tank additives to eliminate whatever untreated waste stink you might be worried about.

 

7.) The Thetford cassette system is the ONLY toilet system that can easily be negative pressure vented thru the toilet neck itself witch makes it impossible for any "stink" to enter the camper. (see SOG vent).

 

8.) When the toilet is installed in a wet-bath as in my Arrow-U, the toilet itself can be used as an exhaust fan sucking out all the steam from a hot shower. This exhaust thru the toilet feature works MUCH better than a fantastic fan which can actually pull "stink" out of your black-tank system and into your bathroom while your taking a shower.  :scared0011:

 

Provided its not raining or snowing tomorrow I can post pictures or (maybe a video link) of how to use the cassette with a standard sewer hose (stinky-slinky), and how the "exhaust thru the toilet neck" negative pressure vent system works. 

Let me know if your interested.

 

Sorry for the long post.

Regards,

I am on my second camper with a cassette.  Overall my experience has been positive.  While you can smell the the contents or deodorizer/chemical while you are actually using the toilet, it's never been as bad as "stench".  The pros are that it has plenty of capacity for 2-5 days (depending upon how many people and habits), you can empty it at a dump site, pit toilet, or regular toilet, and it's one of the few options in a small camper  In my Laredo it has it's own water supply tank so it doesn't draw from my fresh- I could use gray water and in the winter I use RV antifreeze to flush.

The only con for me is the black capacity on extended trips if there is nowhere to dump. 

 

Unlike Electrojake I always "open pour".  Have not had a problem with messes.  Several rinses with hot water are usually enough to get it clean enough and no residual smell.

To explain the vent system a video will work much better than still pictures. 

If I get home before dark tomorrow I'll certainly get something posted here.  :fing32:

Great advice. Thanks all, and espcially Electrojake for the long post! Would love to see pics and video, or whatever else you'd be willing to share. I'm all ears! 

The 2-5 day capacity is not an issue for me. Most of our excursions would be that length. When we do go longer, it would certainly be understandable that I might have to find a place to dump.

I can agree with the positive comments listed above.  My previous camper was a 2007 Northstar 8.5 Arrow with a cassette toilet.  We had no negative experiences with it although we did not do #2 in it.

 

I did notice one thing not mentioned earlier....Unless modified with the vent system mentioned earlier, the cassette tank is normally sealed except when in use.  Use it at a low elevation (i.e. higher atmospheric pressure) and drive to a higher elevation (i.e. lower pressure) the tank internal pressure can make opening the valve to use the toilet somewhat difficult to almost impossible if the pressure change is high enough.  I had a small stick I used to press the sealing valve to relieve the pressure differential when needed.

By Jove!

Being able to do a #2 any time / any place is the whole point of me hauling around a 3800 pound camper everyplace I go!  :fing32:

 

Also. . .

Sorry for the delay but here is the link to the Thetford Cassette toilet VENT video I made…
 
 
I could have embedded it in this post but I didnt want to embarrass myself.
The video is long, tedious, and repetitive, (not much different than a number  of my posts here).  :rolleyes:
 
Second issue: Cassette toilets vs. Black-tank toilets… Apples to oranges.
In smaller trucks campers like pop-ups or my own Arrow-U a cassette toilet is great because of its small footprint and self-contained compactness. However, in a large luxury truck camper (with things like a basement, slides, dry-bath, etc...), a black tank system is a much better choice.
 
My point: One type is not better than the other, they are merely “different”.
 
I’ll be posting another video in a few days outlining my procedure for using a standard RV sewer hose (stinky slinky) with my Thetford cassette toilet so I do NOT have to open pour sewage.
 
Happy camping,

Greetings crew,

Listed below is the link to the Terminal Adapter video...

The above device lets you connect a standard RV hose (stinky slinky) to a Thetford cassette dump pipe for a fully closed waste transfer to a dump station or blue tote.

Ej,

Thanks for those videos. You are one clever dude.

That negative pressure fan would be real nice after 4 days in the 100d desert!  I will have to look closer at that one.  Glad you showed how the cassette vents to atmosphere when in service; I did not know that.

I have a few more truck camper “gadget“ videos but I’ll probably start a new topic so as not to further derail britdog’s thread.

Your videos are supremely informative. You do beautiful handiwork! Much obliged. This is all very helpful input into the decision process.

Thank you! Gracias! Grazie mille! Danke!
