I have a semi-related question here. On my Salem, I have the FW vent/overflow hose down underneath the camper right next to the FW drain hose--the drain has a stopcock and the overflow does not. When I fill the FW tank at home before heading out for a weekend of dry camping, the indicator lights inside tell me it's full. Then I head out on the highway, and I-81 in NEPA is all uphill/downhill/uphill/downhill--when I get to my destination 70 miles later, the indicator lights tell me that I've lost 1/3 of my capacity. I'm thinking that this is from water running out of the overflow as I drive up and down hills. Does this sound possible, and if so, would putting a stopcock on the overflow and closing it for drive time be a good solution? Thanks!
