The tongue load of any trailer is an important weight to measure because it affects the total gross vehicle weight (GVW) of your vehicle. This 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 add the tongue load to the GVW because your vehicle will also be carrying that weight.
The trailer tongue should weigh a maximum of 10% of the total loaded trailer weight, within the limits of the maximum permissible trailer tongue load. 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 correct them simply by moving some items around in the trailer.
WARNING - Trailer
✽ NOTICE
With increasing altitude the engine performance decreases. From 1.000 m above sea level and for every 1.000 m thereafter 10% of vehicle/trailer weight (trailer weighter + gross vehicle weight) must be deducted.
