Trailer Recommendations You must subtract your hitch load from the CWR for your vehicle. Weigh your vehicle with your trailer attached, so that you won't go over the GVWR or the GAWR. You'll get the best performance if you spread out the weight of your load the right way, and if you choose the correct hitch and trailer brakes. For more information, see Towing a Trailer on page 4-56 later in this section. 4-55
