Enter the ratings from your vehicle manual, door sticker and installed hitch to compare them with this RV.
This fifth wheel needs a compatible in-bed hitch; pin weight, truck payload and axle ratings are especially important. Manufacturer floorplan weights may differ from this physical unit. Never use dry weight as the loaded tow requirement.
