Trailer for sale for cars, 6 bolts, not 5 or 4 bolts, large flange, new, first use. It brought a Ford heavy-duty car from Kuwait to Saudi Arabia. Excellent and stable, and it has luxury cotton tow bar adjusters, not nylon that stretches. Please do not undervalue the item, and for your information, I have not seen 6 bolts, only 5 and 4 small flange.
