I've been slowly (very slowly, actually) taking things apart inside.  Most of the old fasteners are coming out ok, but there have been a few tough ones.  The more I look at the original floor plan, the more I like it.  Changes I'm considering:  replacing the front gaucho with 2 recliners or maybe a reclining love seat, and making the shower separate from the toilet and perhaps moving the door opening for the bathroom to the rear with a side facing toilet.  Probably have to make the bed slightly narrower to open up the aisle slightly if I did this.  Don't want to break up the exterior lines with a rooftop air conditioner, so I might try to install a home window unit in the cabinetry.
