Calculating Gross Trailer Weight
Finding out your gross trailer weight (GTW) doesn't require any difficult math equations, percentages or complicated procedures. In fact, it can be as simple as driving your trailer onto a scale. But where are you going to find a scale large enough to hold a trailer?
Most communities have public scales. For just a few dollars and a few minutes of your time, you can get the answers you're looking for. There are just a few simple steps that you'll need to follow in order to get an accurate gross trailer weight reading.
When it's your turn on the scale, you'll need to disconnect the trailer from your tow vehicle. Remember, you're seeking the weight of the trailer alone, so you're going to want to make sure that the tow vehicle is pulled far enough forward so it's not touching any part of the scale. You'll also want to ensure that the entire trailer is on the scale, including all of the wheels and the trailer tongue -- the part of the trailer that attaches to the tow vehicle. If the tongue is resting outside of the scale, you will get a weight reading that could be anywhere from 9 to 15 percent lower than the actual gross trailer weight.
You can take a fully loaded trailer to the scales, or you can take an empty trailer -- the choice is yours to make. Obviously, by taking a fully loaded trailer to the scales you'll know exactly how much that particular load weighs. If you take an empty trailer to the scales, you can record the empty weight so that you'll always know your starting weight when you begin loading the trailer. By keeping track of the approximate weight of the cargo you add, you should be able to closely estimate the gross trailer weight any time you're loading up for a trip.
You can locate the nearest public scale nearest by checking in the phone book or by looking the information up on the Internet. Going to a public scale may cost you a few dollars, but the information that you receive will be worth much more.
One more option that you may have is to contact the manufacturer of your trailer. The manufacturer should be able to provide you with all of the trailer weight information that you request -- information that you can use to safely load and tow your trailer.
