Your RV must be weighed fully loaded (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).
To calculate the opposite side of the RV wheel position weight, subtract the first side's
6.
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.
Once actual weights are obtained, compare them to the Weight Information Label weight
ratings to ensure you are below the posted minimum ratings.
See the Weight Terms and Loading Your RV sections for important weight information.
Towing
Your RV braking system is rated for operation at GVWR not GCWR.
Whenever possible, do not travel with waste in the holding tanks. Liquid
or debris in the holding tank(s) may affect the towing characteristics and
may result in property damage or personal injury.
The propane cylinder(s) should be turned off when traveling. Most
refrigerators will keep food cold or frozen for eight hours without running
while you travel.
Your RV will travel safely and comfortably at highway speed limits. It will take longer than
a passenger automobile to reach that speed. Allow more time to go around vehicles you are
passing. Avoid situations that might require sudden momentum changes as the length of the
tow vehicle/RV combination affects your ability to quickly cut back into traffic. Swerves
and sharp turns, especially at high speeds, could result in loss of control of the tow vehicle/
