Overflow issue

I would look at the exit of your vent. Mine has a screen on it and it is located right next to the gravity fill port.

If I had your problem (I may; just never needed to travel with FULL tanks to find out), I would install a valve in the vent line.

The easiest way to do that is if you have access to the back of the vent outlet and a trip to Lowes for a correctly sized vinyl tubing valve.

Harder would be removing the gavity fill assemble and modifying it to add the valve to the assembly before reinstalling it. (This is what I would have to do in my case)

Or maybe buy a new port assemble with a locking door. That should keep the airflow from sucking the water out of the tank.

My solution to losing water going down the road was to add to the vent hose. My vent hose now ends higher than the top of the tank. I was told I also could put a shut off on my vent line. Just don't forget to open it when you start using water or you could collapse the tank.

UPDATE: Installed the stopcock on the overflow and went dry camping this past weekend. Same camper, same water, same level in the tank upon departure (according to the indicator lights) and same road. This time, the tank was full upon arrival at the destination. So I'm guessing the stopcock worked. I even decided to paint it orange: O-range for O-verflow. I know. I need to get out more.

We never had this problem when we had the gravity fill on our other campers. I find it interesting that FR doesn't resolve this issue. We have been out two weekends since I added to my overflow line to get it above the tank. Both times arrived with a full tank of water. You can now hear air coming out of the vent now, whereas you couldn't before I added to the vent line.
