Losing water from CS-S freshwater tank in transit

I’ve been meaning to ask the group this for awhile. I have a 2014 CS-S with an 11 gallon freshwater tank and find that I’m losing up to 5 gallons between filling it and driving to my destination. I assume this is just from the water splashing out the overflow and fill tubes, but I’m always surprised how much I lose. The tank is under the sink in the rear galley for the CS-S, so it gets the most rocking, especially with bumpy roads. I haven’t seen any signs of leaks either from the drainage valves or inside the TaB. 

Anyone else have similar experience or suggestions for decreasing the water loss? I just bring extra water with me and refill once I get to camp. So it’s not really an issue but I want to make sure I’m not overlooking a problem or easy solution. Thanks all!

    To the best of my knowledge, 2014’s only had a five gallon fresh water tank. 11 gallon fresh water tanks were not installed until later 2015’s.

    Hi @mona. Not sure if that’s true for the non-clamshell models but mine definitely has an 11 gallon tank. It’s visible under the sink in the CS-S which may not be true in the S.

    I travel with the tank empty or close to empty. I noticed that traveling with that tank full negatively affects how the trailer handles. It's a lot of weight to have sloshing around that far behind the axle. I can't say for sure where your water is going, but I think people vastly underestimate how much the back end of the trailer bounces around.
