The grey tank to black tank balance method makes sense. Now if the wife remembers to not fill the tank in the first day will be a bigger hurdle to overcome.
Yes indeed. It took some time for my wife to get with the program of being a miser with water, not for the sake of waste water storage, but for the available fresh water. When flooding the black tank with gray water to free up space in the gray tank (A rare few times, I have done it twice before dumping), you will run out of fresh water before you run out of capacity in the waste tanks.
Some campground rules allow the dumping of gray water onto the soil at your campsite. Just ask. If you do it, be inconspicuous as not to draw attention from other campers who don't realize that it is fine. I simply lay the end of the macerator hose into the woods and let it seep out naturally without making a sound and allowing the water to be absorbed into the ground, avoiding a stream of water flow that may find its way out from the woods. The dumping of gray water at your site is handy if you are close enough to a fresh water spicket to refill your fresh water tank at your site. Then you are only limited to the capacity and usage of the black tank which takes a whole lot of flushes before it fills up.
There are many such procedures from fresh and waste water, battery maintenance, etc. that will become natural over time. I have learned to handle it all myself, one person handling these things. I let my wife know what I am doing, but both of us handling such matters gets confusing, redundant, and mistakes can be made.
Battery maintenance is a focus for me without solar. I stay on top of it diligently for if the batteries drain down to a point, everything stops working. The fridge on propane, requires 12V to operate, be it very little. The big power hogs are the propane furnace blower, and the main TV up front. Unless just overnight, when we boondock, we watch movies off the little TV/DVD combo in the bedroom because it uses so much less inverted power. I converted all my florescent light fixtures to LED which also made a big improvement in battery reserves, the improved quality of light being a byproduct. When boondocking for many days at a time in one campsite, my routine is to run the generator for 1 to 1.5 hours every morning, utilizing a stronger charger than the on-board Tripp-Lite. It also has a nice read-out, providing the charging status in a way that I easily comprehend.
You will learn the do's and don'ts, making errors along the way. It is all part of the RV experience. Just pay special attention to matters of safety, most especially maintaining proper tire pressure. Always check in the morning before heading out, not soon after making a stop because the heat increases the pressure reading immensely, giving you false readings. When checking, use a well trusted tire gauge.
