Studs in the sidewall are Aluminum. Studs in the partition walls are wood.
If you're wanting to mount the tv on a partition wall, is should be easy to find, just push on the wall. The walls will flex a bit where there are no studs. When you get to an area that doesn't flex, you've found a stud.
Here's the LED TV I put in my trailer, bought a piece of oak, drilled some holes and stained it. I used liquid nail to glue it to the wall, the screws are 3 quarter inch. Been on a couple of trips with it on the wall. Pretty sturdy..
