Yeah, i have the same set up in my 222,
So I think the overall design of how they fold out is to sleep two persons Long ways instead of across it ...
I've tried it out myself, I personally came to the conclusion that sleeping across is not comfortable.. .. the center of it with the armrest is kind of bulky and will dig into your side , unless you put something over the top of it .... but I just don't feel like that Peg will support the weight....
On the other hand, setting it up long ways isn't too bad .
I noticed that after you put that Peg down and then lower the sofa in increments , it kinda evens out ..
i also usually put a crate or cooler against the trailers ramp door so the pillow can't fall between back space .. I'll be honest, after that it's not that bad..
