We were out west a few years ago and were approached by a nice couple who said they used to have a Casita
until it was stolen. Because of the compact easy to tow away size these are pretty high on the theft scale I suspect.
My experience with reporting stuff like theft to police is they don't have the time for it and just make a file, no follow up, just another stat. And many places and states are lax on license
plates/registrations. Only way to get caught with something stolen like a camper, ATV/UTV, motorcycles, trailers, etc. is pretty much because they committed another unrelated crime. And if you look around your neighborhood in a rural area on google earth there are tons of campers and stuff tucked far away from sight on private land. A few hours after the theft there is little chance of ever being caught so no small wonder it's happening more and more.
I almost wonder if states should set up a registration
agency to combat small movable object theft. A handful of officers in each state, given power to enter property much like a wildlife warden, who's only job is to check VIN's, and would be paid for only by the fines and convictions, a self sustaining department.
Again, this is just a thought off the top of my head, I didn't post it to be personally bashed. I just know a lot of people who have had stuff stolen over the years (don't we all know victims of theft?) and almost everything was never recovered. I just really hate thieves of any kind.
