You will need a couple of measurements to order the right hitch from any brand.How big is the square frame that goes from the front of the trailer up to the hitch. IE 4 inch tall by 3 inch wide.
When the trailer is parked how high is the part of the hitch that hold the ball is off the ground.
Also, how high the car hitch is when not connected to a trailer.
Last, the size of ball needed. usually printed on the hitch where the ball is seated when hitched up. Examples, 2 inches 2 1/4 , 2 1/2 etc.
I found Andersen more than willing to help me get it right. Also, some great youtubes on installing and hitching up. Watch a couple before you call to give you a good idea of what to ask.
