Well, seen one toilet flange pretty much seen em all-Other than the insert flange. pics are hosted on photobucket-
I'm seeing?
Just for grins. Watched a video of fella removing flange in camper.
Starts out by dragging out half his shop tools and describes what might come in handy. Then proceed to move aside
tools not needed stating 'don't need this.. or that" until all he had was hammer and drift. Tapped the flange and
unscrewed. Kinda funny. Couldn't be that lucky..

Here's the pile I have accumulating in camper...and used them all, haven't even got toilet yet.
Supposed to arrive tomorrow.

Did get floor sanded flat, 3/4" plywood blocks to support plywood edge. Drilled pilot hole so holes that previously
broke out go into wood but still close to edge.
