Not much time to work on my trailer, but I have made some progress. A trip to the hardware for some bolts and nuts to bolt the box to the trailer frame. I chose to use 5/16"x2 1/2" carriage bolts and elastic or stop nuts. The frame is already drilled for these so just drilling through the framework and floor of the wooden box is all that is required. I also purchased a couple of 1/2x8" pine boards for the top construction as well.

Cost of Trip to Hardware $ 15.62

Total Cost of Construction to Date $ 373.64
