I decided to build a landscape box for my 5x10 trailer to save space. I am making it tall enough for my 21" or a later on WB to fit under it. I am wanting to keep gas cans, sprayers, trimmer line, and some hand tools in it to clear up floor space. I will also hang my hand tool and blower off the sides of it. What are some things you look for in a landscape box? I dont know if I should have the top open, the outside open, or the inside open. Any input is welcome!
