Trailer tongue load
The trailer cargo load should be distributed so that the tongue
load is 9 to 11% of the total trailer weight, not exceeding the
maximum load of the following. (Tongue load / Total trailer
weight x 100 = 9 to 11%)
2.5 L 4-cylinder (2AR-FE) engine: 150 lb. (68 kg)
3.5 L V6 (2GR-FE) engine
Without towing package: 200 lb. (90 kg)
With towing package: 350 lb. (158 kg)
If the gross trailer weight is over 2000 lbs. (907 kg), it is neces-
sary to use a sway control device with sufficient capacity.
The total trailer weight and tongue load can be measured with
platform scales found at highway weighing stations, building
supply companies, trucking companies, junk yards, etc.
