This type of plastic tank is only made to be installed in a pickup box, so it means, the tank cannot be used on the ground or on a trailer.
They are used to transport drinking water, waste water, maple sap, fertilizers, pesticides or any other liquid.
These tanks are not DOT approved for the transport of hazardous materials.
If you plan to use your tank on the ground or on a trailer one day, opt for a horizontal tank instead.
Note that pickup tanks take up most of the truck bed space and they must be tied with straps.
With their « mushroom » shape, they can’t be used on the ground or tied on a trailer, because their sides must be supported by the fenders of the box truck.
Rectangular plastic tanks are made of FDA-compliant polyethylene, so they are food-safe.
