the car is pulling the trailer with a net force of F=masstrailer*a
The trailer is pulling back on the car with the same force.

You use Newton's second law,
F = M a
If you want the net force on car and trailer TOGETHER,
F = (1030 + 360)*2.07 N
Note that the weight does not appear. It is balanced by the upward force on the tires.
