THE EFFECT OF TOWED VEHICLES OR TRAILERS
If your RV is towing a vehicle, you need to know the RV’s GCWR (Gross Combined Weight Rating), the total actual
loaded weight of the RV, plus the total actual loaded weight of the towed vehicle. Even though the GCWR has more to
do with the design limits of the drivetrain (engine, transmission, axle, brakes, and bearings), the additional weight can
also affect the tires and the RV’s handling. Also, always remember to consider the tongue weight of the trailer and its
effect on handling.
