How do you know when the gray water tank is getting full?

The RB14 does not include a monitor for the holding tanks and the tanks are opaque black. I can see the level of the black water tank by peering down the toilet, but I haven't found a way to monitor the gray water tank's level. What are other members doing? Do you just dump the tanks each day or every other day just to be sure? Or is there a way to check the gray tank level which I'm overlooking?


I've seen an aftermarket monitor in the internet. It has sensors in a tape that attachs to the outside of the tank. Does anyone have experience with aftermarket monitors?


Thanks!

Thanks, Julie. I wish you could have seen my wife's initial reaction when I read your post to her at breakfast. LOL!!!  It was a fun way to start the morning.


I'll ask this question to any RB14'ers reading this thread:


How often do you typically fill your 15 gallon gray tank with two people using the trailer? Do you need to empty it every day, every second day, or (optimistically) every third day?


I realize that "actual mileage may vary" but I'm just looking for a general idea of what to expect. 


Thanks!

We have a 16BH but it also has the 15 gal tank.  With two of us and only one using the shower it will last about 2 or 2 1/2 days.  We use a Barker Tote Along 22 gallon portable tank to avoid hauling the trailer to the dump station.  For short distances we pull it behind the RAV4 or we have lifted into the back for longer trips.

The only challenge is if you can't position the portable tank to be lower than the drain connection.  In that case it will still work but someone needs to hold the connection into the tank to prevent a spill.  But I wouldn't try draining the black water this way since there is likely to be some small amount of leakage.  We haven't had a problem with the black water filling up.

Well, I found out on this last trip when I went to hang a towel over the shower rod and found the bathtub half full of water Surprised

My 11 year old niece and her friend had KP duty and haven't learned the art of turning off the water while washing dishes.  Fortunately, I had chosen a FHU site on purpose.  And this was on our third and last night, so I dumped just enough to empty the tub (we used the bath house for showers) so that I would have a full gray tank to flush behind the black water dump the next day.

I second the idea of keeping enough in the gray tank if the black is almost ready to be flushed. 2 adults & a 7yo can get 3 days max out of gray.

Not sure if I could justify tank monitors. They may be cheap, but I'm with Julie – you can't beat free.
