So I'm not going to take away any stars from this thing as I'm not using it on the item it's designed for.The Camco Rhino black water tote doesn't have a gauge, and the water hose fitting that the Bobber Gauge goes on is the only vent. I have a 40 gallon black tank, and got the 21 gallon black water tote because a 40 gallon tote would be impossibly heavy. The 21 is heavy, but I can wrangle it onto my bumper carrier.So dumping a 40 gallon black tank into a 21 gallon tote, you definitely need a gauge! I had read in a review that this Bobber gauge works on the Camco system, so went for it. It does fit, and it does work, but the tank isn't vented so the flow will stop.You can see the Camco tote sort of inflating as the pressure rises, and then the flow stops. I've found that unscrewing the bobber gauge while keeping control of it will vent the air, but the gauge is blown around so you can't vent AND read the gauge. My workaround is to dump some, then vent some, then check the Bobber gauge to see if we're there yet.It's easy to see when the black water reaches the Bobber gauge, then you leave the valves closed and deal with the hose and all that. Repeat as required, in two trips you've emptied 40 gallons of black water. Cool, but not that easy. I don't know of a better solution, so there it is.
