Better pics of the seats would be good too, specifically of where they're bolted to the floor. On my bus at least, the degree of rustiness of those bolt heads was a good indicator of how rusty the floor underneath it turned out to be.

exactly the same spot you had to fix on your last amtran... and i remember you had to do some work... that looks 3X worse than that bus was on those corners..
4.78 rear gears, mid profile tires, T-444E, AT545 it will be a 62 MPH top speed bus..

Do you happen to have a link to something about this issue? I have rust in the same spot on my bus and I don't know yet what I'm going to do about it.

Its usually rotten inside worse than outside.
IC/AmTran seem to rust here the worst.
This was under the reflective tape on Sandi's bus-
They also like to rust under the windows on the rear.
This was inside mine on the rear. I soaked it all in rust converter then patched it up. sandi's walls are completely rotted out inside though. Patched it the best I could.
If shopping for a keeper I'd just avoid rusty buses. Too much work and in the end its never gonna be as good as just starting with a solid example.

Yeah, that horse (name's "Rusty") has left the barn - I've gotta deal with what's there in my bus. My back end is in similar shape as these pics, and I have bubbling paint where the license plate goes.
What is actually the source of this rust in this spot? Does the back end leak in various places and water accumulates inside the back wall?

the back of a bus is sloped down a bit.. and takes a LOT of water spray from the road, take that many times the window seal on the back windows starts to shrink and split with UV and you end up with water in the wall. it also can come from slight leaks around warning lights, clearance lights, etc on the top cap..
Leaks in the front of a bus will get lots of complaints from the driver to the bus barn, leaks in the back, the kids may never notice unless it drips directly on them so they get left untouched..

YEah moisture accumulates. I think its the poor window seal but ANY source of moisture will lead to this. The moisture gets trapped in the ass end and causes MAJOR rot.
This is just SOME of what came out-
That used to be the structure of the rear wall of the bus!
Honestly, I'd just kill the rust as best you can, cut off the stuff on the surface and patch it up.

I'm planning on making my rear internal wall as an easily (hopefully) removable panel, so I can periodically check the watertightness back there from inside. I'd like to build the whole bus this way, but not really practical.

Another reason for the rust is that on the sides of the bus there are places for the water to drain out. On the rear there isn't.

My bus looks to be in about the same shape back there. Did you sheet over those two windows because you figured it was hopeless to try and seal them properly?
What condition was your rear bumper in? The side pieces of mine seem to be swelling out a bit, which obviously concerns me about what's going on underneath there.

Is it possible to put something simple on the back that will do this? Like little ridges or something?

Bumper was fine. The rust was from the trapped moisture inside the rear wall.
YEah, I sealed over the windows cause they're not really needed in that bus. Its a cargo area and sleeping quarters and there was NO way to seal windows since the rot was so pervasive. I'm all for skinning over the leaks.

Its not the lack of a drip rail, its INSIDE the wall of the bus. The side walls are open at the bottom and the condensation and rain water than leak in simply run down the wall and out. If it can't drain then the water just sits in there. On the rear there are no openings inside the wall at the bottom, at least on the IC/AmTran/Ward buses which all three I've had this issue on were.
