diduck, according the the 2007 brochure (click here
), there are several floor plans for the 33-foot (actually 34' 3") 2007 Admiral. Two have space for a washer/dryer combo and the full slide model (33SFS) does not. The ones that have space are prepared and plumbed for a combo unit and it shouldn't be difficult to drop one in. If it's the 33SFS, then I would not even consider it as there is no room for one.
