Help mounting TV and shelf

I would appreciate your help with this.  This picture shows approximately what I would hope to accomplish.  I would like to mount a television or computer monitor, power strip and shelf. 

Some of you have mounted shelves and other heavy items on your R-pod.  Looking at the walls, there doesn't look to be much to support any type of toggle bolts or other fasteners you would normally use on sheet rock.  This picture is a side wall. 

A couple questions. 

1.  Those of you who have attached shelves or other heavy items, what have you used to anchor to the wall?  Do you need to find a stud?  Would the TV be to heavy here? 
2.  For additional 120V outlets, is there a reason they need to be GFI?   I have a 2013 177.  I understand why the outlet by the sink is GFI, but not certain why the one on the kitchenette seat is GFI.

Thanks in advance.

We just installed a swivel arm mount and 19" monitor in the corner of the bedroom, using the wood framing (with some additionally added backing) that is around the micro/conv oven and storage area above it.  We can watch a movie in bed, or swivel it around the corner so we can see it from the front dinette area if we wanted or needed to.
