So, the overall construction is good. Couple problems with the one I got. The expanding rods are problematic. First, one rod would not pull all the way out. It had a bur or something that prevented it from fully expanding. I had to work the joint over and over with oil, after taking the boots loose until it would finally lock. Also the pin locks are not beveled on the bottom so to lock them one person has hold the locks up while the other person backs up the tow vehicle until they lock. Built a clip to hold them open so one person can do it. Other than that it works great, and is much cheaper. I was out of time for departure and needed to make this one work so had to put a lot of effort into it. Did add stress to our departure, but, in the end it worked and we are out having fun.
The bur was a defect, correctable, the non-beveled pins, is a missing feature. One can not lock them without holding the lock pins up.
