I like the blue Ox aventa tow bar. I just recently replaced mine. I used it for about 10 years. I didn't replace it because of the construction, I was driving the coach to fuel up, and as I was getting into town, a UPS drive flagged me down and told me I was dragging the tow bar. It seems it came loose and fell to the pavement. I drug it about three miles. needless to say, it didn't do it any good.
