Based on my research your 2013 Dutchmen Voltage 3950 has a Lippert 1621 pin box from the factory. There are a couple 5th Wheel replacement pin boxes with air ride that are compatible replacements.

The Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000 lbs # LC369535 is the most popular option that uses a scissor like motion to absorb shock using the air bag and rebound shock. This pin box also has a rubber compound built into the head to absorb that initial road shock before it gets to the air bag.

The 5th Airborne Premium Fifth Wheel Air Ride Coupler - 21,000 lbs Capacity # 5AB-E1621-610 also uses the air bag and shock combination, but the shock is also protected from the elements. This pin box is designed for vertical shock reduction of 44% and longitudinal shock (chucking) by about 60%.

Both are great hitch options that work very well. The 5th Airborne has a slightly better feedback from our customers but both are very popular with the Flex Air being more popular for the 21K replacement.
