Towing a Trailer Gross Vehicle Weight Rating (GVWR) － The maximum allowable weight of the vehicle, all occupants, all accessories, all cargo and the tongue load is 5,952 lbs (2,700 kg). Gross Axle Weight Ratings (GAWR) － The maximum allowable weight of the vehicle, all occupants, all accessories, all cargo, and the tongue load must not exceed 2,888 lbs (1,310 kg) on the front axle, and 3,175 lbs (1,440 kg) on the rear axle. Gross Combined Weight Rating (GCWR) － The maximum allowable weight of the fully loaded vehicle and trailer is 10,053 lbs (4,560 kg) with the proper hitch. The GCWR must be reduced 2 percent for every 1,000 feet (305 meters) of elevation. Estimating Loads The best way to confirm that all loads are within limits is to check them at a public scale. For public scales in your area, check your local phone book, or contact your trailer dealer or rental agency for assistance. To help ensure a safe drive to a scale, or if you cannot get to a public scale, we recommend that you estimate your total trailer weight and tongue load as described. To Estimate the Total Trailer Weight Tongue Load The weight that the tongue of a fully loaded trailer puts on the hitch should be 5 to 15 percent of the total trailer weight for boat trailers, and 8 to 15 percent of total trailer weight for all other trailers. (See page 490 for limits for your towing situation). Too much tongue load reduces fronttire traction and steering control. Too little tongue load can make the trailer unstable and cause it to sway. Add the weight of your trailer (as quoted by the manufacturer) with everything in or on the trailer. Then check the tables on page 490 to make sure you do not exceed the limit for your conditions. 488
