Thanks Lotus. It is not complicated and you described it well, at least in my point of view.
One thing only: if towed longer time "rear up" and front wheels rotating free on the ground (sort of one axle trailer style), can it do harm to center differential even though the TCC is disengaged? Maybe oil heating issues or something like that?
And boy, am I now glad I ordered with manual stick! Hard to imagine that automatic electrocomic transmission working well for five years in here
