Is there a big difference between aluminum vs steel weight wise. I would love a dump trailer and when you are going to invest in a piece of equipment I like to know all the details. I know this, that aluminum is alot more money and because of that reason I would want to keep it long term.......and also factor in the cost of fuel. Just how much savings would I generate over a 10yr or 15yr period. I think it would be smart purchase. I don't plan on hauling heavy equipment.....for now, all I have is a Walker (riding lawn mower). Could really use the dump for the fall cleanups and I fork off grass clippings every day in the summer and fork off leaves twice a day in the fall season. Thanks in advanced guys!
