Sidewinder Recommendation For Lippert 1116 Pin Box On Keystone Sprinter  

Question:

I contacted Lippert and based off of your pin box serial number, the pin box that you have is a Lippert 1116. The loaded weight rating of your 2019 Keystone - Sprinter Campfire 29FWBH is 11,900 lbs. I recommend 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret part # RP61412 which is a cushioned pin box with the sidewinder and turret assembly that bolts to your Lippert 1116 pin box. The Sidewinder will really help with turning clearance to avoid damaging the back window of your truck since it moves the pivot point 22" back. I have attached a formula for you so you can figure out if you can make 90 degree turns with your short bed truck:

(A + B) - C = Clearance

A = Distance from center of 5th-wheel hitch jaw to truck cab in inches

B = Length of Sidewinder arm in inches (22")

C = Width of trailer in inches divided by 2


For example:

If you are using the 16,000-lb 5th Airborne Sidewinder, then B = 22"

If the distance from the center of your hitch to your truck's cab is 36", then A = 36"

And if your fifth-wheel trailer is 102" wide, then C = 51"

102/2 = 51

Therefore,

(36 + 22) - 51 = 7" of clearance
