    Aluminum fuel tank trailers are much lighter than steel ones, which helps increase payload capacity and may improve fuel economy. The trade-off is that aluminum is more prone to dents and can be less suitable for rough, heavy-duty conditions.

    Steel trailers are heavier, but they offer better impact resistance and structural strength. With proper corrosion protection and maintenance, steel can also provide excellent long-term durability.

    So, aluminum is generally better when weight and payload are the priority, while steel is preferred for rugged use and maximum durability.

    We’re in business to make money. More payload, more money. Aluminum fuel trailers have been used for decades trouble free.

    Yep. Even the outfits that haul fuel to drilling rigs and frac sites use aluminum trailers.

    Steel is for vacuum tankers and LPG / ammonia bottles.

    Hauled fuel for 20 years and only used aluminum trailers, including hauling fuel into the iron ore mines. When margins are pennies you need max payload to make a profit.

    Water being heavier than gas or diesel sits in the bottom of a steel tank and can rust it out in no time also. Aluminum doesn't have that problem.

    Aluminum is about 1/3rd the weight of steel IIRC.
