There was someone on here towing one of those aluminum looking fullsize trailers w/ pics of it behind his X5. Try checking the towing threads...I think you might be pleasantly surprised what the X can tow. That one looks like a small car trailer, no? If you're just wanting to tow a regular trailer, i'd just go that route for like $1-2k.
I'm in the middle of trying to purchase a few of the removable European tow hitches so myseld and another member here can tow race bikes to the track  Sorry I can't help more.
