A toilet “burping” is due to either:
- Your black tank is full
- The pipe from the toilet to black tank is clogged (most likely scenario)
- You have a poop pyramid blocking the pipe leading into the black tank from the toilet
- The vent that leads up to your RV roof is blocked
I would start by emptying your tanks completely and working down the above list from there.
