Regarding how many times I'd have to dump my 36 gallon Gray Tank #2 (Wash tank) When I'm on a full hook up site I drain it via a 3/4" GRAY garden hose and leave the valve open, this is the ONLY tank where I leave the dump valve open, the hose forms a natural water trap so sewer gas does not migrate out of the ground into my RV via this path. So i'd only dump once a week, all week, from 12:00:01AM on the first day to .. Well the start of the next week.
But more important.... I have a six gallon water heater, With a couple tricks I can kick it up to 10 or the equivalent of 10, but how many gallons of HOT do I need to fill that tub? (More I suspect) I'd need a flash heater for the tub.
