Consider using sway control with a utility model 3,000 pounds (1361 kg) or less, or with a wagon model if your trailer will weigh 4,000 pounds (1800 kg) or less. You should always use sway than 3,000 control with a utility model model if your trailer will weigh more pounds (1 361 kg), or with a wagon than 4,000 pounds (1800 kg).

Engine Fan Noise This vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster driving conditions the clutch reduces fan noise. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases when the clutch engages. you may hear an increase in fan noise. This is normal and should not mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan cooling is not required and the clutch disengages. You may also hear this fan noise when you start the engine. It will go away as the fan clutch disengages.
