TOWING SAFETY

Towing a trailer requires care.  Both the trailer and vehicle must be in good condition and securely fastened 
to each other to reduce the possibility of an accident. Some states require that large trailers be registered 
and licensed. Contact your local Department of Transportation office to check on license requirements 
for your particular unit.

Check that the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's 
Gross Vehicle Weight Rating (GVWR). 

Check tires on trailer for tread wear, inflation, and condition.

NEVER

 tow trailer using defective parts. Inspect the hitch and coupling for wear or damage. 

Make sure the trailer hitch and the coupling are compatible. Make sure the coupling is securely fastened 
to the vehicle.

Make sure directional and brake lights on the trailer are connected and working properly.

Check that the lug nuts holding the wheels are tight and that none are missing.

Maximum recommended speed for highway towing is 45 mph (72 km/h). Recommended off-road 
towing speed is not to exceed 10 mph (16 km/h) or less, depending on terrain.

When towing, maintain extra space between vehicles and avoid soft shoulders, curbs and sudden 
lane changes. If you have not pulled a trailer before, practice turning, stopping and backing up in an 
area away from heavy traffic. 

A film of grease on the coupler will extend coupler life and eliminate squeaking. Wipe the coupler 

clean and apply fresh grease each time the trailer is towed.

Connect safety chains in a crossing pattern under the tongue.

Before towing the trailer, check that the weight of the trailer is equal across all tires. On trailers with 
adjustable height hitches, adjust the angle of the trailer tongue to keep the trailer as level as possible.

REPORTING TRAILER SAFETY DEFECTS

If you believe your trailer has a defect which could cause a crash or could cause injury or death, you should immediately 
inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Generac Mobile Products 
LLC.

If NHTSA receives similar complaints, it may open an investigation; and if it finds that a safety defect exists in a 
group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in an 
individual problem between you, your dealer, or Generac Mobile Products LLC.

To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-888-327-4236 (TTY:1-800-424-9153), 
go to http://www.safercar.gov; or write to:
