Wall Studs

Has anybody mapped out where the studs are in the wall and ceilings.  I want to mount cabinets to the wall over the bed (new 178).  I have seen pictures of other such cabinets that have been made and I want to know how others have safely attached things to the wall and ceiling.  I can see the stud in the shower wall, which will help a lot, but I don't want to search for the ones in the body wall and figure someone knows.

I just used molly bolts to secure to the wall instead of worrying about the studs.

Thanks.  So the size Molly that is safe to use?  AND can they be used in the ceiling without fear of a leak.  I am a woodworker but drilling hole in my new RPod makes me nervous….ha,  Steve

Marwayne, do you want to wade into the discussion?  I too was a skeptic and am certainly nervous about drilling holes in the ceiling of my pod, and, given the rough roads that I travel over, I do worry about DIY cabinets shaking loose. 

I stand by what I built and what I said, however if you don't want to drill holes in your walls and ceiling and don't feel comfortable doing it, don't do it. I wouldn't want anyone to do what I did and have unsatisfactory results. I think it's best to only undertake projects that you are confident in doing. Like I said in a previous post I didn't buy the pod for what it is, but what I can turn it into.
