According to my Firestone representative, the only difference between the # F2542 and the # F2525 is that the mounting brackets on the F2542 are a bit different to allow a B and W fifth wheel hitch or a fifth wheel hitch with the # RP30035 universal brackets to be installed. The Firestone # F2525 would not be compatible with frame brackets for a fifth wheel hitch.
