OP here, 3 years and 2 months later. Just got a call from the Isanti County Sheriff Investigator. They found my trailer. They found it abandoned on the side of the road near the Cambridge airport. They found it in the fall with the VIN scratched off. They were able to put the puzzle together from other numbers and stuff on the trailer. Contacted Ridgeline who told them the dealer who they sold it to and my dealer gave them my name and number. That took 4 months to figure out.
The investigator said the trailer was still in near mint condition. Does me no good as the insurance company owns it now. Just wanted to update the thread. 2 sleds I would imagine were parted out long ago, but who knows?
