So far the cargo box is working out well. I can say one thing i do not like is the bolt heads being in the bed. When using a shovel i keep hitting them. The cargo box had some damage on it when it arrived. I believe that was all done by the shipping company because it was all where there were tears in the box. Bit it was in good enough shape to use for my purposes. Also the instructions need updating. One step has you remove the old rails and to keep the screws for future use. But you never use them as new ones were provided,
Good value for the price. I had a little trouble with shipping damage, make sure you inspect carton when UPS delivers it.
I had to shorten the "bag well" mounting bars about an inch to level the frame out. I suggest putting a sound dampener material between the box and the frame.- some foam tape from Home Depot works well.
