Not all truck come thru w/ the puck system for 5ers from factory hence the need for rail install and holes drilled thru bed floor. Had to do it w/ my truck. Sure it might be a PITA doing it. but once done, rails in floor are there till you either remove them or sell it. Downside is, you don't have a completely flat floor as those w/ the puck system. If I was to order a new truck, sure I'd get the puck, but in the meantime, my hitch (and new ones are still avail) has to have bedrails and tabs just like OP has. Not sure about others, but once current hitch is put in at springtime, it stays in until 5er goes into storage in the fall.
