The load weight is important because if the trailer tongue and tow vehicle hitch are not carrying the proper amount of the loaded trailer weight, the trailer can develop a sway when traveling down the road, which can lead to accidents and injuries. An overloaded trailer also places excessive strain on your tow vehicle. This could result in problems with the hitch or the inability to stop in an emergency. Overloading also puts tremendous strain on your trailer's frame, axles, bearings and tires causing premature wear. In addition, load distribution is important because no part of the trailer can be loaded beyond its rating. Axles, tires and wheels also have ratings to consider. Just remember, the total weight of the trailer and its contents should never exceed the trailer’s Gross Vehicle Weight Rating (GVWR), which for most trailers you can find on the VIN label.
