Mine too was siphoning. Most likely, your vent line is attached on the side of the tank...and with a line hanging underneath the trailer, uhhh....yeah, its gonna siphon. Genius design!
I'd put a small brass ball valve on it, but if you travel in the mountains, your tank should have a way to breathe and a closed valve won't allow that. On mine, the dealer, under warranty, moved the vent to a forward position on the side of the trailer. Doing so added another problem (the horizontal line collects water and won't vent).
After my tank cracked due to repeated ballooning, when I had it fixed (on my dime) I had a second vent added on the opposite side of the trailer that again hangs straight down. I close it when travelling, but having it faciliates great venting when filling and using trailer.
Both of my new vent connections are on TOP of my tank. Previously, the vent was on the side...yes, near the top, but their machine can't get the connections super close to the corner. I had the old vent plugged and new ones created...on the top. Mucho better now...but a big slosh can still push some water out an open vent.
