The bowl has come loose from the base of the toilet in my motorhome. The bowl is porcelain and the base (with the flush valve) is plastic. Looks like I will have to remove the toilet and turn it over ...
Called Dometic yesterday and explained that my bowl was a little loose and they sent me a new complete toilet. I received it this afternoon and looked at it and noticed how its put together. Looks just like yours. Now I thinking that I might take mine off and try to tighten and reinstall, if that doesn't work I'll install the new one. Thanks for taking the pictures.
