Here is my review of the Weatherguard Tool Box Model 127-5-02 - Aluminum Standard Saddle box in Gloss Black truck. I've had this toolbox for about 2 years now, and used it in a wide variety of conditions. So far I have been very happy with its performance and quality. I've had many different toolboxes over the years and so far the Weatherguard has been well worth the slight premium you pay.
