Dometic has a history of bad seals, which allow waste to collect in places it simply shouldn't be. Whether from design or manufacturing, it doesn't matter, it's an issue.
So it appears maybe there has been a recall issued on 300 series toilet? The OP may want to contact Dometic on this.
He has a one-year old TT. A quick Google shows reports of the recall as far back as 2013. Riverside is a small manufacturer - I doubt they were working off a 3+ year old supply of toilets.
I pointed that out simply because, based on their history (I found similar complaints about other series), they haven't earned any benefit-of-the-doubt. There's simply no excuse for the problem. They seem to have design issues - a weakly compressed square gasket where a more tightly squeezed o-ring seems to be one which would reduce or eliminate a potential manufacturing issue. Voids which allow waste to collect instead of draining, or least leaking out the bottom so the user is quickly aware of the issue is another.
