The L05 number indicates that you have a Lippert 1621 pin box. The 5th Airborne and Sidewinder that you referenced, # RP61422, will fit the Lippert 1621 pin box. The air ride coupler will reduce chucking and vertical shock while the sidewinder will provide 22 inches more clearance by moving the pivot point of the trailer back. Moving the pivot point back is required on many short bed trucks.
If you have a long bed truck, you will not need a Sidewinder so you can use just the air ride coupler, # 5AB-E1621-610. I have included some links on Sidewinders and air ride couplers for you.
