LS600 PUMP
Some drivers place their hands at the bottom of the steering wheel, and while the tow vehicle is in reverse, “think” of the hands as being on the top of the wheel. When the hands move to the right (counterclockwise, as you would do to turn the tow vehicle to the left when moving forward), the rear of the trailer moves to the right. Conversely, rotating the steering wheel clockwise with your hands at the bottom of the wheel will move the rear of the trailer to the left while backing up.
If you are towing a bumper hitch rig, be careful not to allow the trailer to turn too much because it will hit the rear of the tow vehicle. To straighten the rig, either pull forward or turn the steering wheel in the opposite direction.
Trailer VIN Tag
Figure 50 below is a sample of the Vehicle Identification Number (VIN) Tag which is typically located on the left front of the trailer. See Figure 51.
PSIC: The tire pressure (Pounds per Square Inch) measured when Cold.
VIN: The Vehicle Identification Number.
EMPTY WEIGHT: Some information that comes with the trailer (such as the Manufacturer’s Statement of Origin) is not a reliable source for “empty”or “net” weight. The shipping documents list average or standard weights and your trailer may be equipped with options.
To determine the“empty” or “net” weight of your trailer, weigh it on an axle scale. To find the weight of the trailer using an axle scale, you must know the axle weights of your tow vehicle without the trailer coupled. Some of the trailer weight will be transferred from the trailer to the tow vehicle axles, and an axle scale weighs all axles, including the tow vehicle axles.

The trailer VIN Tag contains the following critical safety information for the use of your trailer.
GAWR: The maximum gross weight that an axle can |

support. It is the lowest of axle, wheel, or tire rating. |

Usually, the tire or wheel rating is lower than the axle rating, | Figure 51. VIN Tag Location | |
and determines GAWR. | ||

GVWR: The maximum allowable gross weight of the trailer and its contents. The gross weight of the trailer includes the weight of the trailer and all of the items within it (such as the pump, and other items). GVWR is sometimes referred to as GTWR (GrossTrailer Weight Rating), or MGTW (Maximum Gross Trailer Weight). GVWR, GTWR and MGTW are all the same rating.
The sum total of the GAWR for all trailer axles may be less than the GVWR for the trailer, because some of the trailer load is to be carried by the tow vehicle, rather than by the trailer axle(s). The total weight of the cargo and trailer must not exceed the GVWR, and the load on an axle must not exceed its GAWR.
