They advertise a "queen size" bed. That's 80x60.
Since the CT bed is 78 and the camper uses most of the tailgate too,
I think it's doable. They don't mention A/C so using the CT for cooling will need some kind of go through.
I signed up on this site just so I could comment on this video.
I watched the Stevenson video shortly after it posted and read all the comments. My overwhelming thought was "What a coven of weenies".
Engineering is art except it's harder to fake.
