AussiemandeusWhat’s with the towball being top and bottom?
KillerWhaleDifferent size for larger trailers over 3.5t. 50mm or 75mm typical use in Australia.
2" or 3" ball in NA to my understanding.
NA has 3 common ball sizes for pickup trucks: 1 7/8" for tiny trailers under 2,000 lbs; 2" for most trailers under 6,000 lbs; 2 5/16" for large/commercial trailers under 10,000 lbs
Theb you also have pintle hitches, and with wheel.
