For larger trailers, a Class III or IV hitch is recommended. The Class III hitch has a sturdier attachment and a larger, 2-inch receiver tube, and is often found on full-size pickups. It can handle up to 8,000 pounds, with 800 pounds of tongue weight.
The Class IV hitch also uses a 2-inch receiver box, but sturdier construction allows its capacity to go up to 10,000 pounds and 1,000 pounds of tongue weight. Class IV hitches are traditionally only found on heavy-duty pickups that are rated to tow that much weight.
