Black Tank Guage

We were out for 14 days in our Crusader 260 RLD. The Black tank guage kept going up and up. I had full hookups and I emptied every 3 days or so. The tank guage says it's still full even though I know that it is empty. When we left I flushed the tank for about 10 minutes. Anybody else ever have this happen? Any solutions?

It's best to just lift the lid off the kettle and look down to check on the soup. The tank may need a good rinsing.

Best thing to do is paint the lights black on the display and forget them. They are the biggest waste of money I've seen on any trailer. They would be better off with the old fashioned sight gauges on the outside. No electricity required, just accurate readings.

The sensors have probably crapped out on you. Truly, they are not very reliable anyway and a little "stuff" stuck to them causes all kinds of false readings. Run plenty of water in the tank, at least 1/4 full, some Dawn detergent, about a cup will do and drive the rig around with stops, etc. The Dawn will help break down the "stuff" and the sloshing will help reduce it to liquid so it will clear out. I use one of the rinse wands with the spinning head and it works good. Anytime you are using the black tank be sure an use enough water to keep it from forming a big %#$@ in there.

Use powered water softener and laundry detergent to clean black tank!

Thumbs down

I have a new Tracer, 1st trip out when it was brand new it was giving false readings, we went out this weekend and it read full when we got to campground. Like others said they are a waste however on my old Rockwood they were pretty reliable fore the 8 years I had it. Just ignor it I guess.
