I am looking to switch from bagged mulch to bulk this year and trying to determine how much I can safely put on my trailer. I have a 6x10 with a single 3500lb axle. I plan on building up the sides with wood but I am worried about weight. I have done some research on the topic and most seem to say around 800lbs per yard does this seem right to you guys? So I am thinking 3 yards at 800lbs puts me at 2400lbs plus weight of actual trailer on axle. How do my numbers look? Thanks for the help.
