2020 3761 FL Black Tank(s) Configuration

Good morning:
When looking at the manual and online specification for a 2020 Montana 3761FL, it states it has one Black tank rated at 88 gallons.


My current unit has the 1 1/2 Bath configuration. It also has two drain valves for the black tanks and two separate flushing sprays hookups.


Does any know the actual configuration and actual black tank size?


Also the level probes seem to be extremely flaky. Has anyone else experienced this?

You actually have 2 tanks. I assume they are both 44 gallons. As far as the level indicators, this has always been a problem. The sensors get dirty and cause false reading. Flushing the tanks help. You can also use a bit of dawn soap and water to clean them. They make a sensor cleaner as well.

I have the 2021 3761FL and I only have one black tank flush but we have two 44 gal black tanks. I wonder if the flush goes to both ?

We have a 2021 3761FL and it has 2 44 gal black tanks with the associated flush and dump valves. The level sensors have NEVER worked reliably from new! Dawn, 5 gallons of water and a long drive helps some, but they soon read 2/3 all the time again. Just dump your tanks weekly and you will be fine.
