What one usually does is put up a 1-inch or 3/4-inch solid backing board first and secure to the thin trailer walls with MOLLY BOLTs. These bolts spread out behind the wall and spreads the weight over a larger area. Using regular screws will just pull out of the thin walls dropping the TV to the floor. The molly bolts are great as they stay in place after you mount them to the wall. The wing bolt type will drop the wing section behind the wall if you remove the mounting bolt.
If you use these bolts in the four corners of a larger flat board then it really spreads out the weight to hold rather large items.
This back board will hold up the LCD TV monitors real good. You can paint the back board to suit your interior decor.
You might want to use a smaller back board like shown in the photo...
You can pick up the swinging arms and supports from WALMART or LOWES in the TV Sections. Most of them will fit the mounting hole arrangement behind the TV sets.
I have mounted alot of heavy things the thin RV walls over the years by using the back plate idea going on the wall first. Then you can use regular wood type screws to mount your swing arm to the back board..
