We took probably 4 - 1 day trips with the trailer this was used with. The trailer has been sold, unfortunately the sway bar attachment knob for the trailer went with it (see picture with red x showing what is missing). The entire weight distribution hitch setup is here, but the sway bar is missing the trailer knob. See pictures to see all the specs for each part. Manuals are available with it.
If the ad is up, it is available. Make it clear that you are human and interested in the hitch or use the word Bluebird in your email, so I know you are human.
