Recommended Pin Box For A 2022 Keystone Montana High Country 335BH 5th Wheel Trailer


I have a 2022 Sierra 2500HD L5P with a 6’9” bed. Looking to see what your recommendation for the best and most comfortable pin box to pair with a BandW Companion Slider. Thanks!

When it comes to comfort you're looking in the right direction with the Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000lbs # LC328492. The internal air bag absorbs road shock for a smoother ride. The scissor-like motion in this pin box's design allows it to compress, compensating for jarring and bounce. The built-in shock ensures that the pin box rebounds, which keeps the air bag from breaking down.

This pin box is compatible with a B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W, but you'll need to verify the bolt pattern of the pin box currently on the trailer to confirm it will fit. Typically there's a tag with the serial number and RPO number somewhere on the pin box, which we can use to find the bolt pattern. If not then you'll need to use the attached guide below to determine the bolt pattern.
