If You Do Decide to Pull a TrailerIf you do, here are some important points:• There are many different laws, including speed limitrestrictions, having to do with trailering. Make sureyour rig will be legal, not only where you livebut also where you’ll be driving. A good source forthis information can be state or provincial police.• Consider using a sway control. You can ask a hitchdealer about sway controls.• Don’t tow a trailer at all during the first 500 miles(805 km) your new vehicle is driven. Your engine,axle or other parts could be damaged.• Then, during the first 500 miles (805 km) that youtow a trailer, don’t drive over 50 mph (80 km/h)and don’t make starts at full throttle. This helps yourengine and other parts of your vehicle wear in atthe heavier loads.• Obey speed limit restrictions when towing a trailer.Don’t drive faster than the maximum posted speedfor trailers, or no more than 55 mph (90 km/h),to save wear on your vehicle’s parts.Three important considerations have to do with weight:• the weight of the trailer• the weight of the trailer tongue• and the total weight on your vehicle’s tiresWeight of the TrailerHow heavy can a trailer safely be?It depends on how you plan to use your rig. Forexample, speed, altitude, road grades, outsidetemperature and how much your vehicle is used to pulla trailer are all important. It can also depend on anyspecial equipment that you have on your vehicle,and the amount of tongue weight the vehicle can carry.See “Weight of the Trailer Tongue” later in thissection for more information.Maximum trailer weight is calculated assuming only thedriver is in the tow vehicle and it has all the requiredtrailering equipment.
