Cannot refuel at dock on 2015 sweetwater premium

I have seen this issue with gas back splashing while trying to put fuel in at  dock. But don’t seem to have a solution. Read many explanations why this is happening but no answers to how to refuel without back splash. I have tried a siphon, but as soon as flow starts really good, gas flows out of fill. I have contacted my dealer, service people  and other owners. No solution is evidently available. Except, to fill the tank with a funnel 2 cups at a time. This does not seem like an acceptable solution. I am frustrated.

    I suggest replacing the anti siphon valve on the fuel tank first and if that does not work you'll want to check the vent line. This pressurization happens when the tank cannot vent the vapors.

    I have the same problem and can’t believe there isn’t a solution. Ekay and I can’t be the only 2 people with this problem. This past Sunday it took me 32 minutes to put in 20 gallons of fuel. Not acceptable.
