I put one in the back room (4 bunk model) it had the plug and coax outlet there. I used a stud finder to find the aluminum stud. You can also feel for the stud by pushing on the flimsy Masonite wall. I marked the center. Then I used a tiny finishing nail to poke a hole on both sides of the stud to make absolutely certain I was on each side of the stud thus getting perfect center. I drilled into the stud and then used slightly bigger self tapping screws about 1/4 inch wide and 1 in length. I put the permanent lock tight on them. I mounted a regular bracket like at home. The small brackets only use two bolts in the center. The TV is a 21 inch and weighs about 10 lbs. It's solid, been up for 2 years and I drive with it up.
