Need some idea's on building a shelf into my dump trailer so I can load organic compost quicker. I've seen Adam's pictures of his set up....which is great....but I don't want to drill into the metal bed of the dump trailer. Here's a few pictures....and I think I've got a good idea on what I need to do....but would like to see if anyone has any good ideas!!!! Shelf needs to be removable. Also removing the shelf...needs to be completed by a solo person. Thanks for everyone's input!!!!
