I got this off PMRA Forum.
Good news! Trailer, bikes and most everything else recovered today. Trailer has a little damage to the hitch and gate latches, but not that bad. Bikes are just as I left them. As far as I can tell, the only thing I'm out is my helmet, gloves, and a couple bottles of Pepto Bismol.
Apparantly, the perp's mother turned him in cause my trailer was parked in her garage. Then the cops squeezed him a little for the location of the bikes. Hopefully, I can get some money out of him for the repairs. Not holding my breath.
