I've a right hand gear lever on my right hand drive vintage trike and to be honest - it was the least difficult control to adapt to using.
Same for me. I found the turn signal the worst -- especially in sudden lane changes (e.g. coming upon a flock of sheep in the road in the countryside) when I would often flip the wipers on instead.
From the photos, it appears that the Mog3 has the turn signal on the "wrong" side in every locale -- probably so it won't hit the bodywork. So for me, RHD would put the turn signal stalk on the left, or "proper" side.
