Need replacement toilet for my thetford aqua magic toilet in a itasca 2002

[bruce Dixon]

I'm looking for a replacement toilet
Thetford aqua magic toilet
itasca 2002 horizon.

Issues:
1.) Thetford aqua magic toilet is no longer made.
2.) Itascas design on the black water tank is is real short and fitting can't be removed. I have tried Dominic it won't work.
I'm looking for a drop in replacement with out removing tank and doesn't require a bunch of modifications.
Has anyone done this and what was reqired

Have you considered replacing all the moveable parts assuming the bown is no cracked. I did mine and not a big problem. A mobil service could easily do it for you. Rkl

I've got a 2000 Horizon and just replaced my toilet with this one. Straight drop in replacement except for the fresh water line. I had some 1/2" PEX left over from another project. That and a couple fittings from Lowes is all I needed.
