A fuel tank trailer includes a fuel tank defining a first containment region, a trailer having a bed supporting the fuel tank, and a secondary containment wall surrounding the fuel tank on the trailer providing an open second containment region for collection of any fuel leaking from the first containment region of the fuel tank and that is open for visual inspection to detect leakage of the fuel from the first containment region of the tank. The height of the secondary containment wall is sufficiently high to contain substantially an entire content of the fuel tank within a third combined containment region defined by the first and second containment regions and sufficiently low so as to permit visual inspection of the fuel tank.
