Pretty much anything with a king bed is usually a rear slide unit like many mentioned above and like our Kodiak 240KSSL.
The slide is hard just like the rest of the TT so it is not a hybrid and would be safe in bear country. The bed is not that bad to get in and out of, especially if the set up is like ours where your head is towards the back of the trailer and feet in towards the trailer. I'm 6ft and its plenty of room with lots of sideways space. The only issue is the front bunks are not a bunk house, but do offer an area to hook up another TV. The bathroom isn't huge but works OK for 4 of us.
Good luck.
