i was thinking on spraying bed liner maybe after the new steel is in

Re: is this rust common ???
 

Yes it is common, my only real suggestion is to use lots of spray in bedliner after the repair.

It is most likely caused by water and debris getting kicked up from the rear wheels and sitting up in between the floorpan and the rear crossmember. Its not an area that you can clean out real well while washing the truck.
