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.

Given the "standard" quality of most mfrs, it wouldn't surprise me at all if a bit of the overflow pipe/hose got stuck down into the tank a bit, which =would= siphon, once it got started. As a former farmer who used siphons from 1" to 4" in size, it's amazing how little head difference it can take to run a siphon.

The vent is at the top of the tank, I don't see how it can siphon out. Maybe splash a bit out, but even then just re-route the vent to loop up a bit higher if it's a problem.
I'd be super leery of valving off the vent, even if only for travel.

Thank you everyone. I was just leary of overfill after hearing stories of damaging RV’s. Now I know and I found them dangling by my drain plug as stated above. Also it makes sense that the displaced air needs to go somewhere, just never thought of it. Prefer gravity fill but we’re learning.
