I could see the bike rack or other purpose if the actual hitch was above the frame mounted but the bottom receiver is just welded to the top receiver which is connected to the frame.It would appear for very light duty purposes or to maybe beef up an extension hitch which most are very anemic in capacity.They say(e-trailer) a standard hitch extension is reduced to 50% of the original hitch,if that is true.
Would the hitch extension welded to a bottom 2" tube increase the capacity/stability of the upper extension?
