4 36, Weight of the Trailer

Three important considerations have to do with weight:
D the weight of the trailer,
D the weight of the trailer tongue
D and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,400 lbs. (630 kg)
with up to six occupants in the vehicle or more than
2,000 lbs. (900 kg) with up to two occupants. If you
have the optional trailer towing package, your vehicle
can tow up to 2,900 lbs. (1 300 kg) with up to
six occupants or up to 3,500 lbs. (1 575 kg) with up to
two occupants. But even that can be too heavy.
It depends on how you plan to use your rig. 
For example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull a
trailer are all important. And, it can also depend on any
special equipment that you have on your vehicle.
