Third year using that set up. Approx 28,000 tow miles. Have not had any problems. Had mine serviced last summer at the BO plant in Pender, Nebraska. I think it was $30 or so and they took it all apart, replaced all the washers and bolts etc, lubed it all at my campsite. Campsite? Oh, they have a really nice FHU campground on site - free to those getting new tow bars or service. 3 yrs ago, when they were installing the auto stop cabling on the toad, I took their plant tour. Very interesting. They also manufacture quite a number of farming implements and have for decades.
