It seems to me Winnebago has a not-so-successful track record in developomg a custom chassis for a front drive cab (they had two designs w/ VW and one w/ Renault)
I assume they are doing it here, as well, unless Chrysler is supplying a complete chassis – but this is only one of many possible rear chassis.
For a really great driveable small MH, there should not be a need for a step to get in the door (see a Rialta). This would attract so many B owners who like to tour, but have discovered the van is too small to enjoy over time.
Look at Ranch;s video on his Telstar

Note how he is amazed at how well it drives. Also note how it has no big appliances on the roof, a barrel roof (lower c.g.), and a low overall ht.
For a radical application of the FWD Ducato, Winnie ought to find a reliable low slung rear chassis and retry their Rialta design concept.
I think this will naturally happen in time, if not W, some other builder will do it.
Understandably Winnie is shy to reintroduce a great, though flawed, Rialta-like design out the gate w/ Ducato…but stay tuned!
