There is a possible solution in another thread
here--> Toilet Install Precaution
(READ POST #1 there please)
Bulldog are you sure you want another toilet or is your problem more
of a bad/leaking seal at the floor flange???
This is a valid question!
Can't help you with a replacement as I have no experience there.
Good luck with your quest for a better potty! This is one subject that
comes up a LOT in the forums. Seems like the manufacturers could come
up with better solutions but RVs are a unique situation. Unless you have
a full time site with full time sewer hookups and unlimited water you don't
have much choice in toilets. They are all similar as far as I can tell.
