I'd like to set up my Astor a s a backup vehicle, used mainly for mulch. We have a 5x10 open trailer, 3500 lb axle, with gate and 4' sides. any idea what the trailer itself might weigh? I'd like to be able to tow around 3-4 yards of mulch if possible. What will I need to make it happen without having too much of an issue? I figured a trans cooler. I'd liek to buy a simple $110 Reese hitch from Walmart if possible. Will I need a Weight distribution setup? Any input on this?
