maillemaker,
It didn't splash OUT of the sink, it sloshed around and went down the drain pipe. :) (Though upon rereading, I probably should've written "splashes out of the p-traps used on the plumbing for the sinks.) Just saying that it NEVER happened if the windows are all closed up, but did happen a few times early in our ownership when I tried driving with the windows & vents open instead of running the A/C.
Others on these forums have also noticed this same issue with their rigs, so I know we're not alone. I don't see where it's that unrealistic after driving several hours down the roads, the water will slosh quite a bit. Or, perhaps where you live, the roads are all smooth and straight?! Not so here in New England. :)
Anyway, what we have also done to pretty much eliminate the issue is to make sure the stoppers for each sink are inserted into the drains.
Just trying to pass some helpful hints along to folks who might also have the problem.
