I am looking at getting a Bradford built 4 box hauler bed and am wondering if any of you guys or gals have any experience with them.
Are the boxes weather proof and so on. Any other brands you can think of would also be helpful.

 

I don't think I would consider most hauler bed boxes waterproof. The best fit I have seen are the B&W beds but they are spendy. We also sell CM Truck Beds which builds the ER hauler bed. Compare it side by side with a Bradford and you can see the CM is a higher quality, heavier built bed.
