alliance RV paradigm 2021 PINBOX MAINTENANCE User Manual
PINBOX MAINTENANCE
- Regularly inspect the king pin for excessive wear.
- Inspect the skid plate for a neutral/centered position.
- When the trailer is disconnected from the tow vehicle, an equal gap of approximately 1‐1/4” should be between the lip of the skid pad and the rubber compression bumpers. It is normal to be able to slightly move and twist the skid pad assembly with hand force.
- Inspect the retainment rods for excessive wear.
- Inspect the plastic glide pads for excessive wear. The pad should be no less than ¾”
- Periodically check hardware torque values.
- Check and grease bearing(s) once per season. If more grease is needed, add it to the bearing assembly.
Warning
DO NOT MIX LITHIUM, CALCIUM, SODIUM, OR BARIUM COMPLEX GREASES. MIXING OF THESE CAN CREATE A CORROSIVE TOXIC CHEMICAL WITH FUMES THAT CAN RESULT IN SERIOUS HEALTH ISSUES.
CONNECTING TO THE TOW VEHICLE
Hooking Up
NOTE: During the hitching procedure, the bottom of the trailer’s pin box should encounter the hitch skid plate ramp.
- Place blocks against the front and rear of each RV tire.
- If necessary, lower the tow vehicle’s tailgate.
NOTE:
Clearance of the lowered tailgate to the trailer needs to be monitored during hookups, combinations of tow vehicle and trailer have little or no clearance. - With the RV front landing gear, adjust trailer height so the bottom of the trailer’s pin box is 1/2” to 1” below the top portion hitch skid plan.
Warning
DO NOT ATTEMPT TO HITCH THE RV BY USING THE TRAILERS LANDING GEAR TO LOWER THE KINGPIN ONTO THE HITCH OPENING. THIS COULD RESULT IN THE KINGPIN COMING TO REST ON TOP OF THE SKID PLATE INSTEAD OF WITHIN THE HITCH OPENING, WHICH MAY RESULT IN DEATH OR SERIOUS INJURY. - Open the jaw on the 5th wheel head.
- Back the tow vehicle slowly toward the trailer until the tow vehicle’s hitch contacts the bottom of the pin box and the kingpin slides into the receiver.
- Latch the 5th wheel hitch in the closed position.
- If space exists between the pin box and hitch, the trailer has not been properly hitched. Do not tow the trailer. Instead, repeat the hitching steps 1‐7 until the trailer is properly hitched.
- Connect the electrical and safety cords.
- Raise the tailgate of the truck.
- Do not tow the trailer until a Pull Test has been conducted (covered below).

Pull Test
Warning
FAILURE TO PERFORM A PULL TEST COULD RESULT IN SEVERE PROPERTY DAMAGE, INJURY OR DEATH. FAILURE TO SECURE TOW VEHICLE AND RV FROM MOVEMENT DURING THIS PROCEDURE COULD RESULT IN SEVERE PROPERTY DAMAGE, INJURY OR DEATH.
- Make sure the trailer wheels are blocked, the trailer landing gear is resting on firm ground to support the trailer and the tow vehicle is in park with the emergency brake engaged.
- Return to the cab of the tow vehicle, release the emergency brake and apply the trailer brakes.
- Slowly pull the trailer forward with the tow vehicle. NOTE: If properly connected, the brakes and chock blocks will prevent you from moving.
- After successfully performing the Pull Test, fully raise the landing gear per the manufacturer’s recommendations.
- Check and inspect all electrical circuits for proper operation, including clearance lights, turn signals and stop lights.
- Remove and store all trailer wheel blocks.
When pulling an RV, the most obvious difference is mass. You’ll be taller, wider and much heavier. Allow yourself plenty of room and time to maneuver out of potentially difficult situations. Being taller, RVs are more susceptible to sway caused by cross winds and turbulence created by other large passing vehicles. Having the correct hitch equipment that is adjusted properly can significantly reduce these effects.
Know the height of your RV. This will help in avoiding overhead obstructions such as tree branches, low building overhangs and low clearance bridges or overpasses.
Know the width of your RV. This is important when negotiating, turns and other obstructions. Extendable side mirrors and/or add on tow mirrors can help greatly.
Know how much your RV weighs and be aware of the weight ratings of the RV. This information is available for your safety. It is critical to never overload your RV. Overloading adversely affects the towing and handling of your RV. Stay within the weight ratings and limits of your RV.
A tow vehicle and RV weigh a lot and take longer to stop. Increase your following distance behind other vehicles. Give yourself plenty of room and time to stop.
Pull Test (Continued)
Warning
THE RV BRAKE SYSTEM IS DESIGNED AND RATED FOR THE GVWR OF THE RV, NOT THE GCWR OF THE TOW VEHICLE.
Warning
WHEN POSSIBLE, ENSURE THAT YOUR HOLDING TANKS ARE EMPTY DURING TRAVEL. FULL HOLDING TANKS CAN ADVERSELY AFFECT THE TOWING OF THE RV.
Warning
ALWAYS MAKE SURE THE PROPANE IS OFF WHEN TOWING THE RV.
Hitch Receiver
If equipped with a factory hitch receiver, you can tow an additional small trailer behind your RV (if wiring is not included it must be added if a trailer will be towed), such as a boat. Do not use a drawbar longer than 10 inches. The maximum length of the drawbar is from the center of the fastening pin to the center of the ball. The maximum trailer tow rating of the hitch receiver is 3,000 lbs. with a maximum hitch weight of 300 lbs.
The receiver can also be used for a storage rack, bike rack or similar. The cargo weight carrying capacity includes the weight of the cargo carrier and should never exceed 300 lbs. Laws around double towing and overall towing length vary depending on where you live. Consult the appropriate authority for local towing resections in your area.
Warning
DO NOT EXCEED THE MAXIMUM LOAD OR HITCH WEIGHT RATING OF ANY HITCH KIT. EXCEEDING MAXIMUM LOAD OR WEIGHT RATINGS CAN CREATE A HAZARDOUS CONDITION THAT MAY RESULT IN POSSIBLE DEATH, SERIOUS PERSONAL INJURY OR SEVERE PRODUCT AND/OR PROPERTY DAMAGE, INCLUDING VOIDING OF THE WARRANTY.
