Sloshing isn't going to hurt anything and you won't hear it going down the road. We keep ours almost full to have enough to use while not parked in a campground.
As far as extra cost for having a full tank...well water is about 6# per gallon so if you have a 90 gallon tank, add about 540#s of water full, 1/2 would be around 250 so about the same if you took another guest along to go from 1/2 to full. I'd not worry about it because I doubt that would take enough extra fuel for you to notice unless your rig is underpowered pulling steep grades in the high country all day long.
The best advice is take enough you have for 2-3 days on the road without a stop/just in case of an emergency. It doesn't pay to go out empty!
You seem to have very light water. Ours is a little over 8# per gallon.
