Similar here. My wife found the main "double" bed (45"x76") in our Scamp
too confining for two, so I take the small front single and she gets the main bed. Advantage over side-by-side twins is we can share the larger bed for couple time when desired, but separate for sleeping and easier nighttime bathroom visits. Downside is the small bed is pretty narrow (26"), but I'm okay with that. The Casita Spirit allows the side dinette to be used as a single bed, though some find it too narrow (23-24", maybe?).
Our other RV, a Class B, also has a non-conventional arrangement. It's a sort of half-king, half-twin configuration. The head end is full width for the feeling of a shared bed, but the foot end has a center aisle for easy entry and exit without disturbing your partner. I believe the Casita Liberty and Independence can be set up this way. Downside is the bedding gets complicated. We just use sleeping bags with washable liners.
With small RVs, it helps to think creatively about sleeping arrangements.
