This caused me a lot of confusion as there is a company called Water Weights,

It makes you wonder at first when you are driving along the road behind a small pick-up truck with a sign on the back saying "This truck can carry 100 tonnes".
ie, the empty water weight bags.
Back to your original question, a cubic metre of water weighs one tonne, and the pick-up in NSASpooks picture looks quite low at the back end.
Look how the wheels are well up into the wheel arches.

ME: "Sweetheart....the car needs motor oil....please stop at the shop on your way to work and buy some".
HER: "No problem, I will sort it out"..........
