The Brown Davis long range and auxiliary fuel tank range is an engineered solution for being able to travel further with less fuel stops. They are designed to give maxmimum fuel capacity without affecting ground clearance and ramp over/departer angle, whilst being exceptionally strong against the most rigorous of conditions. The Brown Davis long range and auxiliary tanks allow you to get to the most remote parts of the globe where standard tank wouldn't take you, or as a tradesman get to that extra jobsite without constantly needing to stop for fuel.

All Brown Davis long range and auxiliary tanks are contstructed from high grade 2mm (14 gauge) Aluminium coated cold rolled steel to ensure maximum strength and durability. This gauge of steel is sufficiently resistant to damage by impact, and therefore additional tank guards are not necessary (most standard tanks are less than 2mm in material thickness). This material is specifically produced for Brown Davis based on critical specifications given to the manufactuer of the material in Japan. Unlike aluminium, steel is not prone to fatigue from vibration and twisting as seen in off road conditions, and this fatigue resistance far outweighs any weight advantage aluminium may offer. However, the aluminium coating on the specific steel used by Brown Davis offer's the strength of steel with the anti corrosion properties of aluminium. All tanks are MIG welded to ensure the strongest possible seams.

Brown Davis long range and auxiliary tanks are arguably the most thoroughly engineered long range and auxiliary tank on the market. Design elements include internal tank baffles to prevent fuel surge during unstable terrain, double skinned faces behind mounting bracket surfaces, and magnetic drain plugs fitted horizontally to prevent tank damage in the event of the tank coming into contact with terrain beneath the vehicle, just to name a few.
