Question:
I have a grand design momentum 397TH toy hauler. GVWR is 21000. it has a Morryde 1621 SHD 23000 pound pin box. Will this CURT AirRide pin box work on my RV? it looks shorter than the Morryde but not sure. also the bolt pattern is different the Morryde has two sets of 3 holes stacked vertically. this curt has a single set of 4 holes stacked vertically. If this air ride pin box will not work is there any air ride pin box that will work?

Expert Reply:
If your Grand Design Momentum 397TH has the MORryde Cushioned 5th Wheel Pin Box, # MR24VR with a 1621 bolt pattern, yes the Trailair Air Ride 5th Wheel Pin Box, # LC158778 will match. This is a 21K rated pin box and has the same 1621 bolt pattern.
