Here's a tutorial on the toilet we found useful.
We use the aqua-kem blue, and half to a full 8 oz bottle every recharge.

It works great for controlling oders. We use a plug-in air freshener when we have hookups, use the bathroom fan occasionally as needed, but we make full use of our toilet. My advice would be try it before you give up on it. I don't think it's as bad as some people make it out to be. I've done a lot of modifications on the trailer, but I don't see the need to fix this.
