Thanx a lot everybody The Reason that I don't want to fit on top of the trailer is because I want 1 rack whether Im towing a trailer or not. The ball on the back of the Venter sounds like a winner. Karl, I assume you have a 4x4 trailer and not a Venter. If its a Venter, pls let me know how you mounted the ball on the back of the Venter. Last thing, do you suggest the platform (Euro carrier) type racks or the cheaper Xpress racks? Is it worth the extra money
