In addition, a truck with a higher series number typically hasa stronger frame, a stiffer suspension and higher-capacity brakes, increasing thetruck’s ability to trailer heavy loads.1 Before you buy a vehicle or use it for trailering, carefully review the Trailering section of the Owner’s Manual.

Select SilveradoSuburban and Tahoe, and above a 1,000-lb. trailer weight on all other models. (Brakemodels and all Suburban and Tahoe models feature a 7-pin wiring harness torequirements vary by state; consult state laws for actual requirements.)

An electric trailerbrake system uses a brake control unit mounted inside the trailering vehicle; itoperates by sensing the vehicle brakes and then applying the trailer brakes.

The GCWR is the total allowable weightratings — GCWR, GVWR, RGAWR, trailer weight rating or tongue weight.

THINGS YOU SHOULD KNOW BEFORE YOU START TRAILERING7BEFORE YOU TRAILERoverloading. Other factors that can cause sway are crosswinds, poor vehicleSafety Chains Always attach safety chains between your vehicle and your trailerworse. Speed is a major contributor to trailer sway, so you need to slow the vehicle —and cross them under the tongue of the trailer so that the tongue will be less likelyto drop if the trailer should separate from the hitch. Leave enough slack in the chainsso you can corner without the chains impeding the movement of the trailer. Do notmaintenance and road conditions. Trying to steer out of sway will likely make itbraking, however, could lead to a jackknife or other loss of control. To help controlsway, follow these steps: H old the steering wheel as steady as possibleallow safety chains to drag on the ground. R elease the accelerator but do not touch the brake pedalLoading Your Trailer Load your trailer to attain a 10%–15% tongue weight. Some U se the vehicle brakes to come to a complete stopspecific trailer types (especially boat trailers) fall outside of this range. In thesecases, the recommended tongue weight listed in the trailer Owner’s Manual shouldbe observed. A good rule of thumb is to distribute 60% of the load over the fronthalf of the trailer and evenly from side to side. Loads sitting either too far forwardor too far back in the trailer can create unstable trailering conditions — such astrailer sway — at highway speeds and during heavy braking. Once the trailer hasbeen loaded and the weight is distributed properly, all cargo should be secured toprevent the load from shifting.Safety Checklist Before starting out on a trip, double-check the hitch and platform,the hitch nuts and bolts, mirror adjustments, safety chains, and vehicle and trailerlights. Make sure that a sway-control device is installed, if required, and that thedevice is working properly. Check tire pressure on both the tow vehicle and thetrailer. If your trailer has electric brakes, test them by manually engaging the brakecontroller while the vehicle is moving slowly. Check to see that the breakaway switch,if available, is connected and functioning properly. Finally, make certain that all A ctivate electric trailer brakes (if equipped) by hand, until the sway condition stopsYou should pull your vehicle to the side of the road and attempt to determine thecause of the instability. Check the cargo load for shifting and improper weightdistribution. Check tire pressure on the tow vehicle and trailer and the condition ofthe suspension and shocks. If the sway was caused by strong winds, wait forconditions to improve before continuing your trip.Finally, some trailers can be equipped with anti-sway devices. Contact themanufacturer of your trailer for availability.Cornering The turning radius of a trailer is typically much smaller than that of yourvehicle; therefore, a trailer may hit soft shoulders, curbs, trees or other objects whenmaking tight turns. Taking turns sharply can also cause the trailer to strike againstand damage the tow vehicle. When approaching a sharp corner, brake sooner thannormal to reduce vehicle speed before entering the turn. Drive the vehicle slightlypast the normal turning point then firmly turn the steering wheel.

Trailer Weight Rating This rating is determined by subtracting the tow vehicle's weight (curb weight) from the Gross Combination Weight Rating (GCWR). Base vehicle (curb) weight plus 150 lbs. each for the driver and a front passenger is used, so additional passengers, equipment and cargo weight reduce this rating. This rating
