How fortunate for you!
You must have bigger Gray and Black Water tanks than we do??? We never use the fresh water tank. Use supplied water at site connected to our hose and filter.
We don't want to boondock at all. UH uh...
Nope, too old and no desire unless we owned our own property. We have
solar also. We would definitely have a RV station that would dump into a septic tank.
We really don't run the sinks much at all. We use paper and plastic ware and basically just wash our hands and fill the sink 1 time a day to wash and rinse of TN VOL large coffee mugs/thermos. And take a shower about every 3 days (that is for each of us). Lots of time I just take an outside shower using the supplied water at the site and our nozzle that has warm (we have a hot water tank) and cold water.
And our mmm stuff in the black water really fills up by about 3 1/2 days. We use our toilet mostly for #1 and for #2 just for "emergencies" - which both of us have (personal why). Non-emergencies we go to the campground bathroom for #2. Neither one of us use toilet paper. We use sanitary wipes, dispose of them in a plastic grocery bag and tie then take them to our larger trash bag outside. We keep it emptied frequently during the week. So it's not like the TP takes up room in the black tank.
Now that I have disclosed our water habits it's your turn HA!
Kinda' silly to go into detail on a forum don't you think? But you seem to be disturbed about our tank capacity soooo I answered. Apologies to those who think this is too much information.
Other people on another forum have about the same #of days capacity filling as we do with their
Oliver.
So after about 3 days in a park w/ no sewer hook up it's time for us to go to a park that has sewer so we can dump. Not all dump sites take a hose and just have that lovely wand (at say state parks).
It's time to start dumping between 80-max 90%. Only time we came close was a shower with DH where grey water starting backing up un the shower drain. Grey was registering 90% at beginning of shower (not an hour shower). Turn off shower head in-between lathering and rinsing.
Glad you have more capacity. We don't.
Perhaps you have a need to boondock?
We don't.
