Buying Guide: What To Consider When Choosing a Pickup Water Tank
Purpose and capacity: Define how much water you need on average and for how long. Larger tanks are best for farming or rainwater collection, while smaller totes fit camping trips.
Portability and mounting: Look for tanks designed for pickup integration, with compatible fittings and mounting options. Lightweight, foldable designs offer flexibility for limited space.
Material and safety: For drinking water, prioritize BPA-free plastics and sanitarily designed interiors. UV resistance helps extend life when exposed to sunlight.
Installation options: Check available fittings, ports, and ease of connection to hoses and in-vehicle plumbing. Some models include multiple NPT sizes for versatile installation.
Durability vs. weight: Heavier, rigid tanks are robust but may require more secure mounting. Lightweight or collapsible options reduce weight but may need more careful handling.
