JAYCO TOWABLE
It is important to redistribute the load to avoid component failure as well as to
improve the handling characteristics of the vehicle.
Read through all the weighing instructions before you begin. If you have further
questions, consult with your dealer or the scale operator. Your RV must be
weighed fully loaded (that is with food, clothing, fuel, water, propane, supplies,
etc).
1. Weigh the RV including the tongue weight, while detached from the tow
vehicle. This actual overall weight must be less than or equal to the GVWR for
safe operation. If the overall weight is greater than the GVWR, some contents
must be removed until the actual overall weight is less than or equal to
GVWR.
2. Hitch the RV to your tow vehicle. Weigh the RV and the tow vehicle to
determine the GCW. Make sure that this rating is less than or equal to the
GCWR as specified by the manufacturer of your tow vehicle. If this overall
weight is greater than the GCWR, some contents must be removed to bring
the combination into compliance with the listed ratings.
3. Weigh the RV while attached to but excluding the tow vehicle. This will result
in the actual weight that is exerted on all of the RV tires. This weight may be
subtracted from the overall RV GVWR to determine the actual "tongue"
weight.
4. With the RV still attached to the tow vehicle, weigh each wheel position
separately to ensure each tire is not overloaded.
To determine the wheel position weight:
5. Pull the RV onto the scale so only one tire is on the scale. Record the weight.
Your RV must remain as level as possible on the scale (even though an axle
or side is not physically on the scale). Obviously, to obtain the side-to-side
weights, there must be enough space on either side of the scale to
accommodate the RV being partially off the scale.
6. To calculate the opposite side of the RV wheel position weight, subtract the
first side's weight from the weight determined in step #3.
If there is a difference in the weights on one side of the vehicle as compared to
weights on the other side, components (tires, wheels, brakes, springs, etc.) on the
heavier side could be overloaded, even though the total axle load is within the
GAWR.
It is important to redistribute the load to avoid component failure, improve the
handling characteristics of the tow vehicle and not void the Towable Limited
Warranty.
With these actual weights, it is now possible to compare them against the Trailer
Weight Information label weight ratings to ensure you are below the posted
minimum ratings.
