If You Do Decide To Pull A nailer If you do, here are some important points: 0 There are many different laws, including speed limit restrictions, having to do with trailering. Make sure your rig will be legal, not only where you live but also where you'll be driving. A good source for this information can be state or provincial police. Consider using a sway control if your.trailer will weigh 4,000 lbs. (1 800 kg) or less. You should always use a sway control if your trailer will weigh more than 4,000 lbs. (1 800 kg). You can ask a hitch dealer about sway controls. Don't tow a tqailer at all during the first 500 miles (800 km) your new vehicle is driven. Your engine, axle orother parts could be damaged. Three important considerations have to do with weight: the weight of the trailer, the weight of the trailer tongue and the weight on your vehicle's tires. Weight of the Trailer How heavy can a trailer safely be? It depends on howyou plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your.vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle. Use the following chart to determine how much your vehicle can weigh, based upon your vehicle model and options. Maximum trailer weight is calculated assuming the driver and one passenger are in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers and cargo in the tow vehicle must be subtracted from the maximum trailer weight. Above the 2,000 lbs. (908 kg) trailer rating, the engine oil cooler is required on CIK-1500 models with 5.7L engine and C/K-2500 Suburban models with 5.7L engine and 3.73 axle ratio. 0 Then, during the first 500 miles (800 km) that you tow a trailer, don't drive over 50 mph (80 km/h) and don't make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads. ' 0 If you have an automatic transmission, you can tow in OVERDRIVE (OD). You may want to shift the transmission to DRIVE (D) or7 if necessary, a lower gear selection if the transmission shifts too often (e.g., under heavy loads and/or hilly conditions). 4-45
