I agree. Guessing that old age and/or health immobility might put some people off the overhead cab bed option?
But the drop down cab bed is a really excellent idea, imo.
Looked at Laikas and Autosleeper Mirages etc. that had the drop down cab beds before lockdown, all very workable and didn't affect the seating arrangements, but now those vehicles would be too big for me. Not because I can't drive them, but the dreaded 70 approaches (C1), plus we got to some places in Ireland in the old VW that you would really struggle to reach (or even be impossible) in bigger vehicles.
The little Autosleeper we have now is grand and I love it, despite having to make the bed/beds up every night.
