Nice work with the drawing, Robert
I agree that this layout, which I believe is essentially what you have in the Chalet, is the only way to get twin beds in any Escape model... and it could be done in any model.
17 Foot - beds would be narrow
19 Foot - as shown; front bed would be wider than a typical "twin"
21 Foot - rear would be like 19 Foot, front would be standard double bed
5.0TA - rear would be like 21 Foot and 19 Foot, front would be standard queen bed in loft
None of the Escape models have a long enough sleeping or seating area to have twin beds side-by-side with aisle between them, as is available in some larger RVs.
