I also prefer a gravity fill but I've also found that it's much better to fill your tank =slowly=. I'm pretty sure that the first time I boondocked with my new KZ, which doesn't have a gravity fill, I managed to siphon out a goodly portion of my fresh water. I was filling and got a good flow out of the overflow but, even being as water-conscious as possible, we managed to run out of fresh water in just 4 days. I'm =supposed= to have 61 gallons, total, and I plan on getting a meter to check that I'm actually getting 61 gallons. Next time I have it at the house, I'm going to check, then drive around a bit with someone following me to see if I get any siphoning. Then, I'll measure what I get from the low-point drain. I've read more than once on here that people expect to have a tank of X gallons but end up with one that's X-10 or 15 gallons.

Check where your pump draws water from the tank. On mine, the fitting is on the side of the tank so the pump will start sucking air when there is still about 1" to 1 1/2" of water still in the tank. That works out to about 7 or 8 gallons of water. If I need that last bit of water, I just adjust the levelers to put the driver's rear corner low enough for the pump to draw more water. Just not more that 3 degrees off level as that would cause issues with the fridge.
