GUIDELINES FOR MATCHING TOW VEHICLE AND TRAILER
WARNING:
Failure to check and follow tow ratings could result in tow vehicle damage or truck
and trailer separation while towing.
Trailer and its contents together must not exceed truck, hitch and/or trailer tow ratings.
Towing vehicle must have a manufacturer’s rated towing capacity equal to or greater than
the gross trailer weight (dry weight of the trailer plus payload of the trailer). (See Fig. 2)
Gross weight of trailer must not exceed 16,000 pounds for this product.
King pin weight must not exceed 3,200 pounds (See Fig. 3). If in doubt have king pin weight
measured by qualified facility.
1. Check Tow Ratings:
Vehicle Tow Rating: ________________.
5th Airborne Pin Box Rating:________________.
Gross Trailer Weight (Figure 2):________________.
*Trailer weight should be the lowest of these recorded ratings for safe towing conditions.
2. The 5th Airborne pin box is designed for a maximum of 20% Gross Trailer Weight on the pin (Pin Weight). See Fig. 3
20% MAX. GROSS
TRAILER WEIGHT
(PIN WEIGHT)
3. The Height of the hitch and pin box should be adjusted so the trailer is approximately level as it is towed. Allow
approximately 6 in. clearance between the top of the bed and the underside of the front of the trailer for pitch and yaw
of the trailer (See Figure 4). For off-road use allow more clearance between pickup walls and trailer.
