The hitch weight formula for determining the load which the hitch must carry:

HITCH WEIGHT = TONGUE WEIGHT + VEHICLE CARGO load BEHIND REAR AXLE

Tongue weight includes the trailer tongue weight with full gas, water and waste systems and
everything packed inside the trailer. Vehicle cargo includes all materials carried in your tow vehicle, such as boat motors, gas cans, tools, etc.

The hitch weight formula for determining the load which the hitch must carry:

600 Weight distributing Hitch
Specially suited for use on medium boat trailers, light travel trailers, single horse trailers, heavy folddown campers, heavy luggage or utility trailers.

800 Weight distributing Hitch
Ideal for medium travel trailers, heavy boat trailers, heavy horse trailers.

1200 Weight distributing Hitch
Excellent with heavy travel trailers, extra-heavy boat and horse trailers.

1500 & 1700 Weight distributing Hitches
Great for agricultural, marine and heavy recreational use.

To determine the correct weight distributing hitch:

1. Determine the tongue weight of your trailer
2. Estimate the vehicle cargo load
3. Match the sum of these weights to the proper Reese hitch.

Example:

Tongue weight 500 lbs.
Plus vehicle cargo load + 200 lbs.
Total hitch weight = 700 lbs.

Using the selector shown above, an 800 weightdistributing hitch is adequate.
