Actually, you should check payload on your SUV before you buy anything. Dry tongue weight alone is going to run anywhere from 650 to 975 lbs. This will be deducted from vehicle (suv) before anything else is added.
It is best to give us your payload capacity od the suv, GVWR of the trailer you are looking at and how many people total will be in the suv. Two adults, two kids and a dog along with misc. cargo in the vehicle and you very well be over loaded.
