i have a 08 fx4 and just recently bought a 5th wheel hitch to pull my father in laws camper. now the hitch i bought is used and came with rails and brackets and universal mounting brackets. the brackets are the L type. now here is my problem. I have read that for the 08 f150 i need a special mounting bracket. anyone know if this is true or if the L shaped brackets will work.
thanks

 

You do need special brackets.
