What an issue! I agree with all other post, there should be no "shelf" period! I would stay on top of the selling dealer till they found information to help your situation, in other words having no idea how to fix your problem is not acceptable. Find some one that does! Having owned several motor homes I have never seen or heard of this problem, unless as mentioned "some knuckle head put a trap vent in a vain attempt to block odor? Not common in the industry. Stay on the dealer IMHO. Good luck.

A picture would certainly help even if it is disgusting. You might be able to remove the toilet and make a ramp out of some plastic material such as a cutting board. Using some Plumbers Goop glue you may be able to build a slide.

You need to prefill your tank with some fresh water AFTER dumping the tanks, about five gallons or so Use plenty of water with flushes. It really sounds like the "shelf" you are describing is the bottom of the tank. If the stuff hits a dry surface it will stick and cause you problems. With enough water all will flow well. Your dealer or a friendly rv neighbor should be able to show you this. Also you should not dump until you have about 3/4 of a tank if using gravity dump. With the macerator you can dump anytime BUT with plenty of liquid. If your toilet has multiple water settings try one of the higher ones so that you get a good bowl full of water with each flush.

Part of the rv learning curve...you are not the first new guy who didn't get good tank instructions from a dealer. AND only human waste and paper though that pump or you will hwve whole new learning experience on how to unplug the thing.

Pre filling the tank as stated will solve your problem.

monacodude.....I had the same issue with a FLeetwood Terra, but worse. It ended being one of two issues as to why I sold it.

I brought home a fiber optic unit from work and probed the tank from the toilet side. Fleetwood used a tank with a shelf as you described. The main body of the drain tank was not under the toilet as in most designs. The tank had a shelf and the waste fell onto the shelf and was SUPPOSE to slide into the tank. Ours was such a problem, that it plugged the toilet 2 or 3 times a trip.

Here are a couple of things you can do. Remove the toilet and check the length of the pipe that goes down into the tank. If they made the pipe too long, it can deposit waste in a concentrated area. Cut the pipe so it just fits in the tank.

Mine was so bad that I cut a larger hole in the tank and added a "bell" toilet fitting (available at Home Depot) that opened up the size of hole in the tank. As the name indicates, the bell fitting expands the hole opening from a 3" to 4" opening. This gives you a 4" opening, but still uses the 3" toilet attachment.

I own a 09 Safari Simba manufactured by Monaco. I purchased it from a previous owner. I gave the macerator one try, it didn't work very well and went to the stinky slinkey. My black tank is very shallow, maybe only 8" deep. So crap piles easly below the toilet if there is not a sufficient amount of water in the tank. For the first few months, I couldn't even get water to spray through the sanicon spray system, It must have been cloged from the previous owner not flushing the tank good enough. It has cleared up since, but sprays like a lawn sprinkler. It's ok for dumbing while using the MH, but not good enough for the final dumb prior to going back into storage. I have to do the water hose and spayer down the toilet to do a good cleaning. The 5er I owned before this HM had a sanicon sprayer that you could hear the water pressure pounding the sides of the tank, even with a pressure reducer attached.

One think I hate about my set up is, the plumbing below the toilet is kinda an "S" shape offset, so my 4" opening into the black tank is reduced to 2". Toilet paper get cloged easly, mostly when the women use too much paper. I have to keep a slim metal rod in the rest room to push the paper through when is gets cloged. Any one else have this problem?

I think the orignal post problem is that his sanicon spayer is just lousy, and does not rinse worth a crap!

Don your idea of a chute sounds interesting. Instead of the waste going straight down maybe he can take a piece of pvc that just fits the hole opening. Decide how long it would need to be if curved. Place the pvc in an oven at 250 degrees for ten-20 minutes. Just enough to soften it. You can easily bend the pipe a lot. Onced cooled place it into the hole and glue it in place with the world famous Plumbers Goop. Any waste will go to the deep side of the pool.

My tank has a shallow shelf but the waste dumps into the deep end of the pond. I found that when leaning to that side if not level that it will fill the shallow end with liquid and block the vent which is on that end. This can cause some interesting gurgles coming up. This only happens when the tank is nearly full.
