If I am interpreting the photos correctly it seems there is a door frame on the other side of the wall from where the TV mount will be. That should strengthen the wall much more than just having a stud there. If the back of the dinette seat is attached to the wall, and the TV mount is just above the seat I would think that screws into the stud and into the door frame would be strong enough to support the TV, especially if the TV would rest on the top of the dinette seat while traveling. If you remove the cushion from the dinette seat back what do you see?
Yes, that's exactly correct, and that door frame goes floor to ceiling as does the stud in the wall as I was able to confirm today with the inspection camera, taking the dinette seat cushion and bottom panel out, and some more measuring.
I got real lucky, as it turned out where the mount needed to be positioned to center the tv on the wall happened to line up perfectly with both the stud in the wall and the main door frame member on the other side. The 2-1/2" lag screws went into the stud, the door frame, and three wall panels.
The TV with mount collapsed to the flat/transport position. Picture was taken from the jack-knife sofa. You can see that the person sitting in the dinette seat opposite of the TV has straight ahead viewing with the TV pushed flat against the wall.
Pivot the TV out a bit on one end and it gives a straight shot from the sofa.
Pull the TV out from the wall and pivot that end a little more and it can be viewed from the bed which is behind the sofa.
I was hoping the TV would end up closer to the wall. I knew it would be close in terms of the person sitting in that dinette seat and brushing up against the TV. When sitting in that seat the back of my shoulders do brush up against the bottom front of the TV when I sit up straight in the seat. If I'm working on the laptop on the table or eating it's not too much of a bother. I think moving the whole TV up another 2" would help. My wife is shorter than I am so it may not bother her sitting there.
Now I need to figure out a retention method to keep that thing in the flat/transport position. I had hoped to use some sort of drill bushings and a ball-detent pin in the cantilever mount arms, but there was just no clean way to do that, not to mention it's near impossible to get your hand back there to actually install/remove the pin.
So, what types of retention methods should be considered? Straps I suppose???
What I did to install both flat screens in my fiver:
I used a section of 1x8 to make a solid base to install the TV mount. I used another section on the opposite side of the wall, which was in a closet. I used carriage bolts, washers, and nuts instead of lag screws. I drilled through both sides of the wall to pass the bolts through. Before finally tightening down the nuts and bolts, I sprayed expanding foam into the cavity between the wall sections for extra support.
It worked out well. To secure both flat screens, I have a low tech solution. I use bungee cords that wrap around the screen and are secured to the mount itself.

Hey Wrace, looks really good. I'd be a little nervous about going over bumps without some support for the TV, but with the TV tight against the wall the weight of the TV is pretty close to the attachment to the wall so there is not a long lever arm trying to twist the mount off the wall. Some people use a strap to hold the TV tight against the wall. Mine mounts against the wall with the arm extended so I made a block to hold the arm near the TV with a little toggle to keep it from coming loose. Mine weighed only 7 pounds though.
You mentioned using a ball-detent pin in the cantilever mount arms. Maybe you could do something like that on the place that the desk mount would go when the TV sits on a desk.
