Tank sizes

[Trent1961]

I have a 2004 Yellowstone and would like to know what the fresh, grays and black water holding tank sizes are. I think I have issues with the accuracy of the gray and black tank sensors as they show liquid even after drained. Any help???

Sounds like you might be new to the world or RVs. Tank sensors are known for inaccuracies. Experience will give you an idea of how long you can go between dumping. Don’t rely to much on the sensors. Gulf Stream indicates that your gray and black are both 52 gal. Not bad for black but your gray will fill pretty fast.

FYI, when I empty mine, tanks will normally show half full. A couple rinses may get them to show empty but as soon as we use them, they show half full again.

That sounds like the issues I’m having. The only saving grace is that we have dual gray water tanks. Thanks for the reply! Happy camping!
