washer dryer hookups

Has anyone ever converted a bunk house model 5th wheel to washer dryer hookups? Seems to me if there is a rear bath or plumbing you could remove a bottom bunk and install a low profile washer dryer and run new lines across from the bath.
I want to stay under 30' in a fifth wheel and I can't find anything under 33' that has washer dryer hookups.

Thanks
