Modifying an RV toilet to fit your RV

If you can get to the underside without removing the coroplast (if present) and a lot of other work, an offset flange would work. You *might* be able to do it from above if you're careful and make a clean cut in the pipe into the tank. I'd use a die grinder with saw blade on it, but if you don't have one, a dremel tool may work but would be slow. A flex shaft on a Dremel may help.

Another solution would be to create a recess in the wall the thickness of whatever the studs are - 1-1/2" or 2-1/2" if the wall has a vent pipe in it. Then trim it out to make it look nice. If the vent pipe happens to be behind the toilet, this wouldn't be possible.

Those toilet flanges can sometimes be repositioned. The other trick is to use a drill and a Dremel tool to grind some new bolt positions in the existing flange.
You may need to use some Original JB Weld to beef it up a wee bit.

Maybe try a Offset Flange:@

Bingo! They hit the wall.

The Bravura should bolt right in using the correct set of holes. The water line will need to be extended.
What type of flush mechanism is on your current one? Look closely at the Sealand toilets because some of them are odd and require modifications.

Funny all the ones I have installed all have the same bolt pattern.

Surprised it don't fit. I have had 3 travel trailers in the last 10 years and replaced all of the toilets with the Bravura. Never had a problem.

Many of the Thetfords are direct replacement.

It's a Thetford, Aqua-Magic IV, I think. The chart says a Bravura should fit. But it doesn't.
