Contact the seller of 5th wheel and ask what pin box is on the trailer. My lippert pin box had a sticker on it. Then go to Pull Rite website and cross reference that number pin box to the correct capture plate.If in doubt pull rite makes a universal plate. You should be able to figure it out form there. Pull rite should also be able to tell you what that "65" plate will fit also.
