Question:
Is the Curt Q20 5th wheel trailer hitch compatible with a TrailAir pin Box? I noted you had concerns with this hitch being used with other shock absorbing king pin box systems.

Expert Reply:
The Curt Q20 Fifth Wheel Hitch, # C16130, is compatible with a TrailAir pin box as well as other air ride pin boxes. It is not compatible with Sidewinder or Revolution pin boxes because they do not pivot at the fifth wheel hitch. Instead they pivot using a turret at the opposite end of the pin box.
To prevent the Sidewinder or Revolution pin boxes from pivoting at the hitch, they use a wedge just behind the king pin that locks the pin box in one position at the hitch head. This wedge can damage the rubber on the fifth wheel head of the Q20 hitch.
