    We typically can go for a week before we think about dumping the Black Tank but I usually use the campground facilities so there is only one person contributing solids. We could probably go longer but don't want to take any chances. Yes, our gauges are off despite efforts to clean them.
    Our tank has a straight shot into the Black Tank so one can see the level.

    Are you going by the gages or actual tank level? Gages are notorious for being inaccurate.
