Having taken a long family trip where we needed to take the car along with our F-350/TT, I spent a lot of time following in the car and watching the "mist" hitting the ground with every bump and curve that the trailer took. It was fun to watch as during the 8 hour trek...it never stopped. Yes it was the water from the overflow valve and while we weren't too worried as we were dumping that water as it was full of bleach to sanitize the system from the winter, it was an eye opener to make sure that we fill or pack extra water when we dry camp. It was about 6 gallons of water from the 45 gallon tank.
