Those things, on average, carry 9,000 gallons. So, assuming we're talking about liquid surging, we'll say the tanker is half filled - 4,500 gallons.
4,500 gallons is just a little bigger, just a tad more, than your "large" fresh water tank of ~100 gallons (Which, if half full, 50 gallons, obviously) on most RV's.
The tanks on a large fuel tanker are not one big 9,000 gallon tank. There are several separate tanks of different sizes. Something like 1500-3500 gallons. The bulk truck I drove was 2500 total gallons with 700, 600, 500, 400, and 300 gallon tanks.
As I said before, even the 300 gallon tank being down would effect a FL700 freightliner.
Sometimes water tankers are one bug tank, but baffled to reduce surge.
