I am afraid that I do not know that information off of the top of my head. Somewhere in your trailer is a placard or poster that has that information on it. This placard or poster could be near the hitch of the trailer or posted in one of the inside cabinets of your trailer.
If you cannot find the placard you should try contacting Gulf Stream Incorporated the manufacturer of your trailer at (800) 289-8787. Be forewarned that they may not have this information.
If you still cannot get this information then the best way of getting the weights is by taking your trailer in and getting it weighed.
I am assuming that you need the weight to determine if your vehicle can safely tow the trailer. There is a lot you need to understand about trailer weight and towing. So please refer to the articles below to get some important information on what you need to know about weighing and safely towing a trailer.
