Weighing Your Tow Vehicle & RV

There are two important factors when loading your RV, total weight and balance. It is impoerative that you verify compliance within all applicable weight ratings. Overloading your RV will void the Limited Base Warranty and Limited Structural Warranty, and the warranties of many component part manufacturers. Have your RV weighed periodcally at a public scale to determine the proper load distribution. Keep in mind that individual scales will operate differently. The surroundings of the scale need to be adequate to accommodate weighing each side of your RV.

To weigh your tow vehicle and RV

Read through all the weighing instructions before youj 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 detacthed 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 more 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 the Gross Combined Weight (GCW). Make sure that this rating is less than or equal to the the GCWR as specified by the manufacturer of your tow vehicle. If this overall weight is greater than the Gross Combined Weight Weight Rating (GCWR), some contents must be removed to bring the combination into compliance with the listed ratings.
  3. Weigh the RV while attatcched 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 attatched to the tow vehicle, weigh each wheel position seperately 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 accomodate 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 Limited Base Warranty and Limited Structural 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 raings.
