A loaded trailer can be dangerous.  Please remember that a trailer will be inherently unstable if you pack more weight behind the axle than to the front.  You also do not want to put too much weight to the front as that will put undue stress on your tow hitch and the back suspension of your tow vehicle.  Load the majority of the load over the trailers’ axle/s with slightly more weight to the front than to the back.  This will ensure that your trailer tracks straight and true and that you do not damage your tow vehicle.
