Can a 5'7" straight bed be switched out for a bed with ramboxes? Mods?

 

I would expect, that if the beds were the same relative size, that the bed with the ramboxes should bolt right up.

 

if you can find a 5 7 with ram boxes yes. Im not sure if the ram boxes have extra wiring for lights or such but thats all youd prob be missing. I think the tailgates are the same aswell.
I cant see dodge changing the ram/mounts for a slightly different box.
