How many gallons of water to fill a truck bed?

Answer 1

No way to answer this without knowing the dimensions of the truck bed. For all we know, you could be talking about a small pickup or a large dump/tipper truck.

Answer 2

The amount of water needed to fill a truck bed will depend on the size of the truck bed. A standard full-size truck bed typically holds around 60 to 80 gallons of water. It is important to consider the weight capacity of the truck as well before filling it with water.
