HOW DO I PICK THE RIGHT TYPE OF WATER TANK?

Selecting the right water tank is crucial for ensuring you have a reliable water supply. Water tanks come in various types, each with its own set of advantages and disadvantages. Understanding these options will help you make an informed decision based on your travel habits, space constraints, and climate considerations.

These tanks are the most popular choice among van owners, as they are installed inside the van, significantly reducing the risk of freezing and making them ideal for colder climates. They fit seamlessly into SergSupply Wheel Well Boxes and SergSupply Universal Wheel Well Box Bed Systems, maximizing space utilization and providing easy access.
This tank saves interior space and remains out of sight, contributing to a clean aesthetic in your van. However, it risks freezing in colder climates, which can limit its usability, and its capacity may be restricted based on the size of the spare wheel compartment, requiring more frequent refills during longer trips.
Pros include space efficiency and a concealed installation that keeps the interior tidy, allowing for a more spacious living area. However, it is prone to freezing in cold weather, which can lead to potential damage and inconvenience, and accessing it for maintenance can be more challenging due to its location.
