Main reason for wanting a transit as opposed to its competitors is my mate who used to maintain a lot of vans for a van hire company reckoned the transits are a lot simpler to maintain and generally are reliable in the first place.
The movano etc look good for the money, but personally I'd just sooner have the transit.
Interesting about diffs, I would have thought the engines were torquey enough without needing to be geared down plus you could just be in a gear lower while towing if not?
And surely a low geared diff would ruin economy which is likely to matter a lot to the RAC?
Not the end of the world to swap a diff though im sure.
