You should use the black tank flusher every dump and rinse 'til the discharge is clear...you'll need a clear elbow on the sewer connection. Try the Geo Method of adding water, detergent and water softener to the empty tank. Here's a link... https://sites.google.com/site/cbruni/
While in use, the black tank monitoring may still not be accurate as the probes are easily fouled, but you'll soon figure out the number of days camping before it requires emptying. With a TT you can is the level in the tank through the toilet...with a 5th wheel, it may not be a straight drop into the tank.
