      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.
