Anton,
while oficially Vehicross is not recommended for towing because of the short wheelbase, many people reported towing weights up to 4000 lb. But you have to be carefull not to "jacknife" when you're towing.

As to the hitch itself, you have 2 choices:
Dalan hitch, and the Tone's one. While installation of Tone's hitch is a little more complicated, it looks much better - people think it's factory installed. That's what I have and am very happy with it. Search for some pictres here, plus Tone has more details on the hitch he's offering.

Here's a fiew good threads on vmag about towing:
