I love a story with a happy ending.
Well, unknown right now.
Let us do hope that said thief did NOT use your trailer as a meth lab.
Just my opinion, but if it was indeed used as a meth lab, I'd get the police and their hazardous materials team to document it and then do my utmost to get the insurance company to declare it a total loss. Both the fumes from making meth and the chemicals themselves can permeate fabric and other inside materials making the trailer impossible to live in again.
As you said, the inside condition is unknown right now.
Hoping for the best.
