Understand that "king" beds vary in an RV. Some are not much more than a short, wider queen; some are actual kings and some are somewhere in between. Whatever it is prepare to throw the original out and get a real mattress.

This trailer came with a king mattress; full size. I knew the mattress, no matter how good they said it was, would be inadequate. Had it removed, the platform cut down and a nice residential mattress installed. You need to think about movement around the bed if you are plumper. Making the bed, removing the coverings etc. can be excruciatingly difficult with a king bed stuck in a queen bed slot...but optioned out.
