I just installed a new trailair air pinbox on our fiver. The one I removed was a trailair rotoflex hitch.
I've tried craigslist, but only 1 reply but it wouldn't fit their trailer (wrong bolt pattern).
I tried to see if a rv repair shop would need it but due to liability reasons they wouldn't touch it.
I may end up taking it down to the scrap metal yard and see what it's worth.
If anyone has a better place to sell it , i'd appreciate.
Thanks
