What would you improve with modern lorries?

Rikki-UK:
I have never understood, as trucks used for distance are normally single driver why the passenger seat isn’t removed, the bunk placed in it place dash board to rear wall and the remaining space used for a table cupboards and fridge etc like the USA trucks you give so much more living room while remaining inside the Euro length limits, the bunk could split so still giving access to the passenger door

We had an IVECO where the passenger seat folded into the bunk. Can’t remember exactly how, but I’m sure it actually became part of the bunk. Was awful though because you couldn’t get the seat forward enough for the passenger to look out of the side window.
