Towing A Trailer Rated More Than A Vehicle Can Tow

Example you have a pickup rated to tow 9,500 lb.

You have a trailer that weighs 2,000 lb and is rated
to carry an 8,000 lb load. So the trailer and load is
10,000 lb.

Is it legal to tow the trailer empty?

Is it legal to tow the trailer with 7,500 lb load?

Yes, and Yes.
IF the truck is registered for the weight that it is carrying when the trailer is connected (actual truck weight + cargo weight + trailer tongue weight = truck GVW) That GVW MUST be at or less than the registered GVW to be legal.
