This SAE Standard includes couplings, hitches, and safety chains used in conjunction with all types of trailers or towed vehicles whose Gross Vehicle Weight Rating (GVWR) does not exceed 4540 kg (10 000 lb). This includes such types as utility, boat, camping, travel, and special purpose trailers which are normally towed by conventional passenger cars, light-duty commercial vehicles, light trucks, and multipurpose passenger vehicles. This document is intended primarily for ball-and-socket type of couplings and hitches. It should not be construed as a limitation to this type alone but should apply where appropriate to ring-and-pintle, clevis-and-pin, or any other draft means designed to serve this purpose.
The Trailer Committee develops and maintains SAE Standards, Recommended Practices and Information Reports applicable to trailers normally towed by conventional passenger cars, light duty commercial vehicles, light trucks and multi-purpose passenger vehicles. The Chairperson ensures the committee maintains liaison with groups such as the National Marine Manufacturers Association (NMMA), Recreation Vehicle Industry Association (RVIA), International Organization for Standardization (ISO), SAE-related committees and other organizations as necessary. The taskforces formed under the committee's direction include: Trailer - Gooseneck and 5th Wheel Task Force; Trailer Dynamics Task Force; Conventional Towing System up to 20,000 lbs Task Force; Trailer Terminology Task Force; Trailer Braking Standard Task Force Participants in the SAE Trailer Committee include OEMs, suppliers, consulting firms, government and other interested parties.

then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
