WEIGHING INSTRUCTIONS
To properly weigh your recreation vehicle, it should first be weighted, 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 maximum GVWR limitations are
achieved. Once the actual overall weight is determined and the recreation vehicle is
within GVWR limits, the following weights should be determined:
1. The weight of complete recreation vehicle, while attached, but excluding the tow
vehicle. This will result in the actual weight which is exerted on all of the recreation
vehicle tires. This weight may be subtracted from the overall recreation vehicle
weight (above) to determine actual “tongue” weight.
2. With the recreation vehicle still attached to the tow vehicle, each wheel position
should then be weighed separately to be sure each tire is not overloaded.
To determine the wheel position weight:
• Pull the recreation vehicle onto the scale so that only one tire is on the scale.
Record the weight. Your trailer 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 recreation vehicle being partially off the scale.
• To calculate the opposite side of the vehicle wheel position weight, subtract the
first side’s weight from the weight determined in step #1.
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 GVWR. It is important
to redistribute the load to avoid component failure, as well as to improve the handling
characteristics of the vehicle.
TIRES
The tires of all Jayco camping trailers are supplied by companies for RV use, and tested
under D.O.T. standards at allowed speed limits on highways. They are constructed of
nylon cord designed to offer strength and extra mileage in various types of weather. The
air pressure should be kept at its recommended pressure, which is stamped on the tire
sidewall. Always check the tires when they are cold. As tires are in motion, temperature
will rise and air pressure will increase. DO NOT release air pressure as tires become hot,
as the tires will then be under-inflated as they cool.
CAUTION: It is recommended that the tire pressure be checked at the beginning
of each journey to obtain the maximum life of the tires.
