Black Tank Readings Not Possible
So we took our new to us 5er out on it's maiden voyage to a campground with full hookups about two hours from home. I check the tank levels the morning after our late night arrival and all the tanks ...

Welcome to the world of RV-ing! False black tank readings are unfortunately normal. The button sensors can get slime built up on them, and in some tanks, the 1/3 sensor can be a bit too low which can make it worse.
Thorough cleaning at each dumping will go a long way to reducing false readings. Fill tank to near full before dumping. If you have a built-in tank flusher, let that run for maybe 5 minutes then fill the tank again and dump. Look down into toilet (water turned off) and if not clean on the bottom, repeat the above process again. I can get our tank spotless doing that. We replaced the standard button sensors with Horst Miracle probes and along with thorough cleaning, we don't get false readings now.
Also, before each use of the tank, add 4-5 gallons of water and don't skimp on water with each flush. That is, unless you are somewhere like Cali. where there is a water shortage. If there isn't enough water in the tank, you will end up with a build-up of solids that will be harder to flush out and clean.
Chemicals before each use of the tank may help a little but it's not usually in the tank long enough to break down the solids.
