How many people would like to have a gauge that told you how much water you had pumped out of your fresh water tank? The factory take gauges are worthless and I would love to know exactly where i was...
A couple of the devices posted were for a garden hose to measure how much water you putting into your tank. I am mostly interested in how much water I have pumped out. It would help with grey capacity as well since if you know you can hold 60 Gal grey and have only pumped 20 you would have a good idea of what storage was avail. Obviously some would have gone to the black tank as well. I would love more info on the company out of Vegas that makes them. $100 seems fairly reasonable.
