How Many Gallons of Water Will a Pickup Truck Hold?

A pickup truck’s size and shape can vary significantly depending on the model, make, and year. This means that the amount of water a pickup truck can hold also varies.

Generally speaking, a pickup truck can hold between 50 to 100 gallons of water. However, the exact number of gallons that your specific pickup truck can hold depends on a variety of factors.


The most important factor in determining how much water a pickup truck can hold is its size. Generally speaking, larger pickups have larger tanks and can therefore hold more water. Additionally, some pickups have an auxiliary tank which increases their capacity to hold more water.

Make and Model

The make and model of a pickup truck will also affect how much water it can hold. Some models are designed with larger tanks than others, so they may be able to carry more water than other pickups. Additionally, some manufacturers offer optional auxiliary tanks which increase their capacity even further.


The year that your truck was manufactured will also affect its capacity to hold water. Older trucks may not have been designed with large tanks or auxiliary tanks in mind, so they may not be able to carry as much water as newer models.


No matter what make, model, or year your pickup is – it will be able to carry between 50-100 gallons of water. However if you have an auxiliary tank installed – this number could be increased significantly depending on the size of the tank and the make/model/year of your pickup.
