A Reese trailer hitch application chart contains trailer weight and class ratings for different trailer and vehicle types. The chart indicates the suitability of various types of hitches for each vehicle and trailer type. Vehicle owners must know their trailers' towing capacity to be able to decide which type of hitch is ideal for their vehicles.
The chart provides specific tongue weight, or TW, and gross trailer weight, or GTW, for each class of trailers. A trailer's tongue weight refers to the downward weight applied on the hitch ball by the towable equipment, while the gross trailer weight refers to its total mass when fully loaded.
The horizontal axis of the chart indicates the hitch class, which ranges from class one to class five. The TW and GTW increase across the axis, with class one having the least and class five the most weight. The vertical axis of the chart lists four vehicle types. These are sub-compact and compact cars, mid-size cars, mid-size pickups, SUVs and minivans, as well as full-size cars, vans and utility vehicles. Class one hitches are suitable for sub-compact vehicles and compact cars, while class two are for mid-size cars. Mid-size pickups and minivans work best for class three hitches, while class four and five are ideal for large cars, trucks and vans.
