Thanks for the picture Dennis, that helps. As far as I know, the '75 coach tank
is original. I suspect the '73 is not, but don't know for sure. The weird thing
is the down tube is exactly the same on both of them, and ends far too close to
the bottom of the tank.
Guess I'll have to try to pull the toilet flange and see if I can remove the pipe and shorten it.
Going to be tough with all the rusted screws, etc, but that's nothing new.
thanks,
Karen

A few pics that might be useful if you're going in that... deep.

Pretty sure my parts were pretty original but the toilet flange wasn't,
so who knows...

Karen,
I will be at my coach this afternoon and will measure the distance from the bottom of the pipe to the bottom of the tank -- still have not reinstalled the toilet. As Dan mentioned -- the holding tank is quite shallow.
When I pulled mine the original screws came out without a problem -- they were in good condition and I reused them.
The flange on mine is glued to the downpipe -- I made this little tool to remove and reinstall the assembly. You can use screwdrivers and pliers -- but I found this easier.

I also installed a wash out system -- shown in this picture.

Cost about $17 at the rv dealer. It only extends into the tank about 2 inches -- has a check valve.
