Question:
I have a 2025 Keystone Alpine 3820FK, GVWR 16,500, almost 42 feet in length. The first long trip we took was from Fla to Tx and back. The chucking was terrible and it appears that the washer and dryer moved enough to turn on a push button light switch in the closet. They are located in the very back next to the shower. Is this the correct upgrade for my 5th wheel. Tow vehicle is a 2019 F350 SRW 8 ft bed. Thanks Bruce Newkirk Item number on the pin box is 2024029454. Chassis MFG 3/11/2025.

Hey Bruce! Thanks for providing your serial number. That is a 1621 so the Curt Helux will not fit. Those are only designed to fit the Rhino bolt pattern. For a comparable replacement I recommend the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # GY62XR. This is the 6.5K TW model which is designed for a 16,365-25,450 lbs GVWR like yours.
