I'm sorry. I'm an idiot. Well, not really an idiot, just confused and got my terminology mixed up. Thank you for the funny responses though. I was thinking that if what is above your head is called the headliner, then below your feet should be the bedliner... not very logical now that I have spelled it out. So, please disregard all references to the bed. I want to put carpet in the floorboard of the cab which is currently now only bare metal and so I am searching for a pattern to use to to precut the holes for the gear shift and seat frames, etc.
Although, now that I think about it, a carpeted bed would be pretty cozy. Maybe with some high pile shag?
