I have a Tiffin 2018 Allegro Bus 40 AP with a Dometic Concerta 4100 series toilet. The bowl no longer holds water; was in Red Bay, AL and had the seal replaced, then re-adjusted number of times. Still the bowl won't hold water, flushes ok, just won't hold water. Short of replacing the toilet (only 5 years?) any suggestions as to what else to try?

I can't find that model toilet, but, assuming the seal is round and fits over a sliding flap, try pushing down on it all around its circumference - but not hard enough to remove it.
I stumbled on this fix when trying to replace my seal. I pushed pretty hard but it would not come out, but, voila, now my toilet holds water.

I could not find that exact model online, but I assume there is some sort of valve that slides against a rubber seal?
If so then perhaps applying some plumbers grease (silicone grease) to the rubber seal will fix the problem.
My toilet has a plastic ball seal that rubs against a rubber seal and will occasionally leak. I just clean off the rubber area and apply a thin coating of the silicone grease and it usually works for quite a while before needing a new application of grease.

LOL!
I just applied some plumber's grease to mine (Thetford) for the same reason, and sat down to look at the forum and here's a thread about the same thing. Yes, it works for me for a good month. But it only takes 30 seconds. Good luck!
