As others have said position at junctions and roundabouts is important.
You will soon realise how carp some of our road layouts are .
Get hold of one of those angle changing panels for the passenger window , they do help and suddenly you will realise the wide angle and kerb mirrors you took for granted are useful.
The right hand side of the cab will seem huuuuuuge for a while ! You will change gear with the left hand door arm/pull so many times it will be embarrassing.
Keep left bollards will seem like they are jumping out at you .
You’ll soon get used to it .
