Excellent! Thanks for sharing. I think this will be my next trailer mod.

I used brackets & bumper support from mount-n-lock.com . Upon close inspection I realized my bumper was properly installed & welded such that the bumper support wasn't needed but since I had them I installed any way for added strength. I have a heavy duty bumper welded properly unlike many that have a light weight bumper just tack welded on. I'll post some pictures once I get that to work. I followed Rays instructions from his video but just garbage comes up. It's likely because I'm trying to do it on a tablet & once I boot my computer it'll work.

Nice! Adds a lot of secure storage. Well done!

I have re-done my site so it's compatible with tablets and smartphones. Here is the video on the installation of the storage box.
