Elddis Autoquest 200/400 lounge dimensions?

[AutoquestQuest]

Hi, I was wondering if anyone can give me the dimensions of the interior lounge area of the 200 and 400 Autoquest? Such as from window to window sideways, and rear window up to - but not including - the cooker and water closet? Is the 200 about a 4 metre square space? And what would the height be from the floor to the start of the overhead storage compartments be? I'm looking to purchase a 200 if it fits my refit storage needs. Many thanks!
