plugged toilet

If you can't retrieve it I would flush it with water, repeating until the paper breaks down and passes out the drain tube. If you can't pull it back then it has to go out through the drain unless you have access to open up plumbing. I would think continued flushing would eventually break the paper down and then out. The key is to flush it good repeating until it's all out. Make sure you get it all because wet paper that then dries can dry pretty hard and block things up. Do you have something that you can inspect it with to ensure you got all the paper out? A snake camera or maybe a telescoping mirror. If that dosn't work you can try some RV tank treatment specifically designed to break paper down. I'm pretty sure you can get it at Walmart in the sporting/camping section near the special RV toilet paper, etc...good luck! Let us know how it turns out.

Similar to what was mentioned above, until you can get it out I would fill up the black tank so the water fills up the drain pipe above where the paper is stuck, to ensure it doesn't dry.

My problem seems to be that the stuff is floating at the top. I turner off the water pump to open the valve and water and paper was floating there. I can still flush and have water go down, but it is still staying there.
The tank empties, but the display says there is still some in there.
Kinda lost here as I don't know the anatomy of the system.
When you flush, does it just drop straight down into the tank? Is there a curve or valve that opens and closes to keep the smell in the tank?   Something is keeping water up near the toilet, but still allowing other water to pass through. So wierd

Fill up the black tank with water (you can use the shower head to speed this up, or just run a garden hose inside) and add 2-3 bags of crushed ice.  Drive around for 20 minutes to agitate and then dump.

I fixed it. Grabbed a stick and kept poking at it until it brike up and went through.
Thanks for all of the suggestions!!
