Dear Multihullgirl, I apologize for the public reply to a PM, but I still have not amassed sufficient posts to be permitted the privilege of a private reply to your nice note, and my lengthy reply vanished, as did, apparently, the last attempt to post all that here. Argggghh.
So, more briefly, we remain well pleased. Make that VERY well pleased.
Admittedly we still haven't given the thing a lengthy midsummer hearty-party workout, but with our relatively light usage, it is just fine. We are able to smugly report that our $&@#, indeed, don't stink, at least not after a good stir. The male of the species has been gratifyingly cooperative in agreeing to sit the heck down, dammit, which makes the entire system work perfectly as advertised. There is a jar of cypress shavings or coir nearby for users to add to the poop bucket as they deem necessary for extra desiccation, and the vent hose out the bulkhead provides all the ventilation, a very slight draft, necessary.
And at the risk of grossing out the squeamish among us, (avert your eyes, guys) I admit that we are at present, given our proximity to real plumbing, approaching the waste disposal question as if the bucket were the world's most odor-free litter box. A cat box scoop, a plastic grocery bag, and those dry lumps and scraps of TP whoosh right away at the end of our trip, or whenever we get around to thinking of it, maybe weeks later. The urine gets dumped daily. Don't ask
No evil beasties, no chemicals to buy, no salt to store, no maintenance beyond the obvious. I don't know what a flapper valve looks like or how to operate a pumpout. And I am pleased. As a result, natch, so is my husband!
