Thanks very much for the replies. It would be really great if we could pull a trailer!!! Do you happen to know the web address of the German MBZ site?

Interesting if it's just fear of litigation. It's hard to think of any other reason it couldn't pull a trailer. Maybe I'll check with the local U Haul people and see if they can install a hitch and if they have experience with this. It will be nice if I can get some confirmation from MBZ too.
