      I bet it’s because there would be a lot of heat, especially when the tank’s engines need to be more powerful to move all of the added weight.

          I think you’re discounting the heat already being generated even without the water. Water is a good conductor of heat, so if there are any hotspots the crew normally just stays away from, that would spread everywhere, including to the crew. The heat would also accumulate since the rest of the tank would be acting as an insulator except on the outside surfaces.
