This weight must be less than your tow vehicle s GVWR Pull the trailer onto the scale and decouple it from the tow vehicle leaving just the trailer on the scale Get a ticket which lists the total trailer weight Re connect the trailer to your tow vehicle and drive the tow vehicle wheels off the scale just leaving the trailer axles on the scale Get a second ticket which lists the trailer s axle weight Simply subtract the axle weight from the total weight to determine the hitch weight While you are at the scale you should weigh the entire combination vehicle This result should be less than the Gross Combined Weight Rating GCWR for your towing vehicle Some scales allow you to get individual axle weights also If this is possible get the tow vehicles front and rear axle weights to make sure they are in the same proportion as the tow vehicle alone and that the rear axle is not overloaded This is the best way to check that a weight distribution or load leveling hitch is adjusted properly i e you have the proper number of chain links attached to the snap up brackets 53 LOADING THE TRAILER 54 SECURING THE CARGO Since the trailer ride can be bumpy and rough you must secure your cargo so that it does not shift while the trailer is being towed A WARNING Shifting cargo can result in loss of control of the trailer and can lead to death or serious injury Tie down all loads with proper sized fasteners ropes

A livestock trailer is designed for the safe transport of livestock other than horses It is not equipped for hauling horses Before loading your livestock inspect the interior of the livestock trailer to insure that no hazards are present Read page 60 Loading Livestock Livestock Trailer for specific instructions regarding trailering of livestock other than horses A WARNING Large animals are capable of inflicting serious injury or death to a human handler Know your animals temperament before attempting to trailer them A CAUTION Hauling a horse in a livestock trailer may result in its serious injury or death Do not carry a horse in a livestock trailer Use a trailer designed to carry horses GENERAL SAFETY INFORMATION HAZARDS FOR DUMP TRAILERS A dump trailer is specifically designed for hauling cargo that is to be dumped not for transporting equipment or livestock The major hazards associated with dump trailers are e Overloading e Improper weight distribution both side to side and front to back e Getting under a raised dump bed e Not using or improperly using the body prop e Modifying or altering hydraulic components e Modifying or altering dump controls e Not dumping from a solid and level foundation e Not fully opening rear doors when dumping e Jerking the trailer or hydraulics to loosen the load See page 61 for more details on these hazards HAZARDS FROM ACCESSORIES The Accessories chap
5. SAFE TRAILER TOWING GUIDELINES e Recheck the load tiedowns to make sure the load will not shift during towing e Before towing check coupling safety chain safety brake tires wheels and lights e Check the lug nuts or bolts for tightness e Check coupler tightness after towing 50 miles e Adjust the brake controller to engage the trailer brakes before the tow vehicle brakes Follow the instructions given with the brake controller manufacturer s literature e Use your mirrors to verify that you have room to change lanes or pull into traffic e Use your turn signals well in advance e Allow plenty of stopping space for your trailer and tow vehicle e Do not drive so fast that the trailer begins to sway due to speed Generally never drive faster than 60 mph e Allow plenty of room for passing A rule of thumb is that the passing distance with a trailer is 4 times the passing distance without a trailer e Shift your automatic transmission into a lower gear for city driving e Use lower gears for climbing and descending grades e Do not ride the brakes while descending grades they may get so hot that they stop working Then you will potentially have a runaway tow vehicle and trailer To conserve fuel don t use full throttle to climb a hill Instead build speed on the approach e Slow down for bumps in the road Take your foot off the brake when crossing the bump GENERAL SAFETY INFORMATION e Do not brake while in a curve unless abs
