Hello, welcome to irv2.com! No those bolts are only for holding the bed onto the frame. A fifth wheel hitch must directly bolt to the frame. Most use "rails" permanently mounted in the bed. The actual hitch attaches to the rails. Reese products
now has an "underbed" mounting system that only requires 4 rectangular holes in the bed for the hitch to pass through. Then pins are used to secure the hitch to the mounting system.
