2021 Momentum 28G Issues

Well I got my new 2021 28G home, it’s beautiful. Now for the questions

  1. 75 gallons of water splashed out of the overflow tubes on the way home 500 miles. I filled up again at home and drove 15 miles to the truck scale to get some weights and same thing 1/3 tank left. Have i done something wrong, I have video of the water coming out the overflows the whole way?

I don’t even begin to know how to address this, but I am NOT surprised. At all. This happens on my little 18RBE Imagine as well. Perhaps there is a way to plug the overflow holes while in transit. Its something I am going to be looking at when home again next month
