My Thor Ace 30.2 also gets backed up when a family member "drops the kids at the pool" or uses a few extra squares of paper.

The easy fix I've found that works best:
1. Drain the black tank and leave the valve OPEN
2. Turn off the water or water pump
3. Hold down foot petal flush on toilet and plunger the toilet slowly - getting a good suction and pulling up then releasing - you should see the clog slowly start to go down
4. Repeat until the clog all washes down - then turn on the pump and rinse the bowl
5. Yell at the likely culprit (optional) (may also be used as step 1)
6. Close the black tank valve

I have also had to use a stick before down the toilet if the paper is really clogged. But that's extra super gross.

Happy camping!
