Trailer Hitch

Greetings. I was wondering if anyone had ever installed a trailer hitch for hauling light utility trailers with their metros. I've got a wee little trailer i'd like to be able to haul to and fro, and I know the metro could do it, since the trailer plus load would be less weight than the people I normally haul around in the passenger seats. I haven't found any bolt on kits available, no surprise there. Was wondering if anyone knows if there's a hitch available that might just bolt up, or if I'm looking at some custom welding (which I'm sort of expecting at this point).

Hey Sean,
I have seen a couple of 4 doors with hitches out here in California. But ... I don't know of any manufacturers, you might try a local U-haul, they seem to have hitches for anything!
