Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects thetotal capacity weight of your vehicle. The capacity weight includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. And if you will tow a trailer, you must subtract thetongue load from your vehicle's capacity weight because your vehicle will be carrying thatweight, too. See "Loading Your Vehicle" in the Index for more information about your vehicle's maximum load capacity. If you're using a "dead-weight"hitch, the trailer tongue (A) should weigh 10% of the total loaded trailer weight (B). If you have a "weight-distributing" hitch, the trailer tongue (A) should weigh 12% of the total loaded trailer weight (B). After you've loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren't, you may be able to get them right simply by moving some items around in the trailer. 203
