Sorry for all of the questions....but that black tank being clean after the sewer dump is the only thing that gives me any trepidation on our first official camping trip (hopefully in late February or early March here in Georgia). I definitely don't have the stomach to be cleaning out a clogged and caked tank....lol!

I have a few thoughts/experiences that might answer some things for you. First, I have a 2012 Seneca, which has a flush port and the ability for me to flush it whenever I want, which I do every time. However, on my past motorhomes, I've done the method I described to you as I had no other option.
So, here's my way of doing it if I'm really wanting to clean a tank I believe is really caked and clogged and might give me grief:
I drain the tank and flush until water appears to run clear. (I have a clear fitting that I put in between my hoses so I can see the effluent.)
Then, I install the tank cleaner solution (which from the smell and appearance seems to be most likely something in the Drano family aka sodium hydroxide, but not sure.) A lot of years in chemistry has possibly affected my sniffer.
I then fill a 5 gallon bucket with HOTTEST water I can get and pour it in the toilet while holding the valve open.
Then I drive back and forth and brake hard in my parking lot, maybe 15-20 times to slosh it, kind of like a washing machine might. Then I fill it 1/2 or more with regular water from the hose. Then I let it sit overnight. Then I dump it into my septic cleanout port, refill with water, slosh it again, and I'm good for a year. (NOTE: You have to replenish your enzymes and bacteria in your septic system after you do this. I use 3x the normal dosage of Rid-X to do this. Your results may vary. The sodium hydroxide kills everything and renders your bioactivity in your tank virtually null. The Rid-X restarts...mostly.)
I do use the organic Happy Campers tank treatment every time I dump. I've been doing this for a long time and never have any issues, and most importantly, no smell. It really is excellent.
Not many folks say so, but let me advise something important. Wear new gloves (latex or nitrile, single use then dispose) and wear a mask over your face. (Cheapie to protect from droplets is enough.) Wear safety glasses or goggles. Be prepared for the uneducated to make fun of you. Then recognize that one amoeba can kill you, not worth the risk. Sewer is dangerous.
Another tip: When you move the motorhome/trailer, make sure you cover, plug, or insert closures in all your drains. This will ensure the gases go out your vents and not inside. It's a small thing that makes a big difference.
Let me know how it goes or feel free to ask about anything unclear.
Cheers.
