Hello, We're looking for a porta potty for our new Aliner Ranger 12. A couple we met last year at an RV park, brought us onboard their PUP and, when we asked out of curiosity, showed us their porta potty. It really (really) was odorless which impressed us. They also raved about the disposal system. Everything was in a plastic bag. When putting a new plastic bag, they added powder. After use, the powder turned to a gel. It was a couple only, no kids. After a few days, they tied up the plastic bag and threw it all away in the RV park garbage can. We were told it was an environmentally sound method. No water in any tank; no emptying anything into a CG toilet or disposal tank. Has anyone here heard of such a thing? I've looked through lots of posts here, searched for "gel", etc., but I do not see anything described like this. I've googled "porta potty with gel", but nothing shows up. Thanks for your help!
