Question:
Hello, I have a 2022 Dutchman Voltage 4015 with a GVWR of 20,000Rotoflex pin box that I recently purchased and also have a 2023 Chevy Silverado 3500 DRW with a Curt Q25. My question is if there is a compatability issue with this combination as I am having issues where even on relatively flat ground the RV and the truck bed rails are coming in contact when turning? I have the Q25 on the highest setting. Any help you can provide would be appreciated. Thanks

Helpful Expert Reply:
The Curt Rota-Flex 5th Wheel Pin Box # LC328329 is not compatible with a Curt E-Series or Q-Series fifth wheel hitch like your # C16265. The design of the Rota Flex will actually wear down the head of these hitches and end up breaking them. You'll want to immediately stop using the two together to avoid any chance of damage going forward and swap out either the hitch or pin box.
To solve your bedrail issue we'll need to see how you trailer sit and the height of your bed to determine the solution. You'll want to level the trailer and measure from the ground to the king pin plate. Then you'll measure from the ground to the bed of your Silverado. The difference between these two measurements will give us the height needed for your hitch.
If this number is higher or lower than a hitch can accommodate then you'd be looking at altering the height of the truck or trailer in order to have it ride level and maintain a minimum 6" of clearance with the bedrails. There are a lot of options we can explore once we know these measurements.
