I'm glad he was able to find it so quickly. Hopefully there is little damage to it and the contents are still intact.
My motorhome was stolen December 2019. It was gone just a couple days. When I got it back, most everything stored in it was gone, they ruined the ignition hotwiring it, stole the engine battery (but not the house battery), cut the fuel intake line on the front tank and stole the fuel from it (did not realize there was a second tank), overflowed the toilet and black tank, and did a lot of minor damage inside. Fortunately, my insurance (State Farm) was great and I got everything repaired and a new toilet.
It was locked. That wasn't enough. I am now having a fence and gate installed so they can't just push, drive, tow it out of the yard.
I have a hitch lock on the trailer, but know it won't be enough. So it will be behind the gate also. And the gate will be locked up tight.
