I recently read a post from someone who's tank fell out. They were traveling with 3/4 tank water and the consensus was that a full or close to empty tank was the prefered way to travel. A tank with 1/2 to 3/4 full tank allows for substantial sloshing around. The support structure for the tank was also brought into question. I personnally never had a problem. Never had quite that large of water capacity but have gone thru a number of RV's. As far as baffles in fresh water tanks goes, I've never seen any with baffles. Not in black water tanks (for obvious reasons) or grey water either.
