RE: I can’t be the only one with a poorly designed black tank.
Here's what we do to get around developing the dreaded ^ at the bottom of the chute in our TC. Having experienced it several times, once had to take a stick to it and once was able to shake the camper and it went on down.
Take a dish tub about 12x15x6 and fill it with water then pour it down the throat of the commode. Empty the tub as fast as you can. The volume of water hitting the solids moves it along. We do this every 2 days. Simply flushing extra toilet water down doesn't work nor does pouring it out of a gallon jug.
Thanks for all the suggestions.
This may be a solution.
I did a quick search on amazon and found there’s an “rv plunger.” Basically a stick with a rigid propeller type thing on the end to help move things along. Found it cheaper directly from the mfg. just received it yesterday. So I’ll give that a whirl. Literally.
I may still install a “tornado” type device near where the pyramid is forming. That will definitely help when having city water pressure. I was really hoping a suggestion would appear with a direct stream type black tank flush, that would give some “significant” pressure when hooked up to the rigs water line (to help solve the boondocking issue).
I replaced the faucet valves with the shower style hose end with two washing machine ball valves and connected a washing machine mixer hose, basically a “y” styled hose. I connected a short garden hose (2’) with a black tank flush (camco?) fitting to see what kind of result id get. Not real happy with the pressure or water stream it produced. I didnt install it for the test, just “bench” tested it into the grass.
Hitting the highway in a week, hopefully the “rv plunger” will assist in breaking down the pyramid and get things moving.
I think ill check the vent pipe if i have time before leaving, in order to rule that out as being an issue.

RE: Side by side towing
With the front wheels secured to the bumper, the rear wheels would have to pivot. There is a company that makes a trailer called a swivelwheel, that does this. I don't think have anything that bid though, as TT bumpers are really flimsy.
Saw someone using that system a few years ago at the desert. He had a RZR on it. Seemed to work for him.

RE: I can’t be the only one with a poorly designed black tank.
Fill black tank from inside the camper i.e., use a hose and stick in in the toilet close the toilet on the hose and start filling. On mine, with a 40 gallon tank I run it 11 minutes then drain.
I do this for about 4 to five cycles or until the water is running clear.
When filling from the toilet you should clear out the shelf.
Truely not a aftermarket design to benefit the buyer.
That is why we adapt, improvise, apply.....
Pretty much the exact procedure i do once the pyramid is formed and i have the “luxury” of being hooked up to a city water connection, or when we have to find a dump station somewhere along our travel route (usually bt CA or GA). Luckily Love’s truck stops typically have a dump to access.
I probably use 150-200 gallons of water to dump the tank properly. Similar to you it’s about 9-11 minutes between pulling the dump valve. So 4 x 10 minutes is an easy 40 minutes of baby sitting the hose and tank alone.
I was hoping my bathroom sink in the toilet “closet” was hooked to the black tank because we rarely use that sink. So id use it more if it was, hoping that would help, but its not.

RE: I can’t be the only one with a poorly designed black tank.
I doubt whether you are getting rid of solids in the tank.
Something like Drainbo this or similar products to truly breakdown septic tank solids may work.
You will have to fill tank to at least half to get it to work.
Thanks, but filling the tank even 1/2 way wont get the liquid to “rise” into the shelf area of the tank. But i do understand what you’re saying. Maybe i need fill the tank with water and draino like product and let it sit?

I can’t be the only one with a poorly designed black tank.
Let me preface, this is not my first rv (it is my 1st Class A pusher) and we have 30+ years experience mostly boon docking, but do spend time in campgrounds also.
With that said, two years ago we retired and bought a used 2005 Mandalay Presidio. From the very first trip, at a campground with full hook ups, we were lucky enough to be introduced to a poop pyramid, that literally “exploded” when opening flushing the toilet. Getting black waste everywhere. Wonderful.
I always leave water in the bottom of the tank after flushing to assist in breakdown etc. When traveling (and occasionally when parked) there’s always an odor.
Traveling down the highway, the poop pyramid has been known to resurface. Every time this occurs i dump the tank as soon as possible, but it doesn’t correct my issue easily and immediately.
I now know what the issue is, this is where i need help. The main, large portion of black tank is not directly under the toilet. The inlet from the toilet is at the far right end of tank. This area of the tank might be 10” tall, in theory the solids are supposed to travel along an ever so slight grade, about 12” towards the larger portion of the tank where they are supposed to fall into the a much larger holding area. This is where the sensors are and main capacity of the tank is. The liquids of course run off this “shelf” with no problem. Leaving behind the paper and solids to slowly accumulate. Filling the bowl full of water before flushing only may delay the inevitable, but it eventually rears its ugly head.
When dumping the tank the only way to clear this area of the tank is to fill the tank with water to near capacity. There is a factory installed sani flush that is on the top of the tank, but not really anywhere near where the pyramid begins to form.
I don’t know how to solve this. I thought i could add another black tank flush where the pyramid forms, which may work, kinda when on city water. I don’t believe the onboard pump will have enough pressure to be effective if i plumb in it a way it could use it when not connected to city water.
So frustrated. Any ideas? Sorry i cannot get a good picture of my tank setup to give a better idea. Picture an upside down “L”, or an “L” shape where the long vertical line lays horizontal and the smaller horizontal line is now vertical.
Thanks in advance.
