I was wondering if anyone knows roughly how much mulch weighs. I was planning on using my trailer this year instead of the truck if I can haul enough to make it worth while. If I use the trailer I can go to the sawmill and get my mulch, but it is 30 min farther than my local guy. I can get the mulch for 75% of what I am paying locally but have the added gas and time to pick it up. I have a 7' x 16' trailer. I can pull up to 7000 pounds with it but I don't like to haul more than 5000. I'm trying to figure up how high I need to make the side rails to get enough mulch to save time and money. ( I can't fill my trailer at the local guy no room) To get the quantity of mulch I need to save t&m I need to have 4' sides. How much would that weigh? Ideas?
