[Lumper]

We just purchased a used 2019 29M model and sounds like we had the same issue. At first campground we had to find a long stick to push things down. Talked to Thor Customer Service. They sent me a drawing of the discharge piping. Looks like it makes a sharp corner to drain to the black holding tank. Ended up taking the toilet off of the floor and using a garden hose to clean out the discharge pipe. At our second campground I leveled the unit so the tank side is slightly down. This also helps keep the headboard side slightly up which we like for sleeping. When we need to flush solids we lightly step on the toilet foot pedal and fill the toilet bowl up half way or more. So far the extra water has been pushing all of the solids into the tank.

FYI - really like the Thor 29M. Was surprised how many things I needed to fix (cracked dash, Automatic Transfer Switch, rattling door panel, reinforcing cabinet under loft bunk over drive area (almost fell down while I was driving) , but once they were taken care of, unit has been solid. Thor customer service has been helpful.
